net: sparx5: free the matchall entry on destroy
In the Linux kernel, the following vulnerability has been resolved:
net: sparx5: free the matchall entry on destroy
sparx5_tc_matchall_replace() allocates a struct sparx5_mall_entry for
every offloaded matchall filter and adds it to sparx5->mall_entries.
sparx5_tc_matchall_destroy() removes the entry from the list, but never
frees it, so the entry of every deleted mirror and goto matchall filter
is leaked.
Free t…
net: xilinx: axienet: Free outstanding DMA buffers on dmaengine stop
In the Linux kernel, the following vulnerability has been resolved:
net: xilinx: axienet: Free outstanding DMA buffers on dmaengine stop
In the dmaengine path the driver pre-submits RX buffers and holds
in-flight TX buffers whose SKBs are DMA-mapped by the driver and freed
only in the completion callbacks. On ndo_stop() dmaengine_terminate_sync()
aborts these descriptors without running their callbacks, and the dr…
net: team: stop reusing skb after queue override
In the Linux kernel, the following vulnerability has been resolved:
net: team: stop reusing skb after queue override
A nonzero dev_queue_xmit() result does not return ownership of the skb.
When an override port's qdisc drops it, the queue override helper used to
try another port or the mode transmit op with the freed skb.
Return the handoff decision separately from transmit success. Select only
the first override…
net: team: free skb when broadcast has no txable port
In the Linux kernel, the following vulnerability has been resolved:
net: team: free skb when broadcast has no txable port
bc_transmit() sends the original skb through the last txable port.
When no port is txable, it returns false without consuming the skb, but
team_xmit() still returns NETDEV_TX_OK. AF_PACKET sends then retain the
skb and its socket write-memory charge.
A TX-enabled, link-down port keeps the broa…
conda-forge.org: Stored DOM XSS via unsanitized dangerouslySetInnerHTML in the status dashboard
conda-forge is a GitHub organization containing repositories of conda recipes. In commits 85748ad2368a and prior, two React components render externally-sourced strings directly as HTML using dangerouslySetInnerHTML, with no sanitization (the project has no DOMPurify or equivalent dependency). JSON files are produced automatically by the conda-forge autotick bot (regro/cf-scripts) while it processes every conda-forg…
openvswitch: fix soft lockup in the netlink flow dump
In the Linux kernel, the following vulnerability has been resolved:
openvswitch: fix soft lockup in the netlink flow dump
A production compute node carrying a few thousand datapath flows hit a
soft lockup inside a single netlink flow dump and panicked.
ovs_flow_cmd_dump() calls ovs_flow_stats_get() for every flow it
emits, and that releases stats->lock with spin_unlock_bh() once per
CPU that has touched the flow.…
optee: register TEE devices only once fully initialized
In the Linux kernel, the following vulnerability has been resolved:
optee: register TEE devices only once fully initialized
optee_probe() called tee_device_register() on both the client and the
supplicant device before the rest of struct optee had been initialized.
tee_device_register() calls cdev_device_add(), which does two things at
once: it creates /dev/tee0 and /dev/teepriv0, and it links the device
into the…
power: sequencing: pcie-m2: Fix leaking array from of_regulator_bulk_get_all()
In the Linux kernel, the following vulnerability has been resolved:
power: sequencing: pcie-m2: Fix leaking array from of_regulator_bulk_get_all()
of_regulator_bulk_get_all() allocates the consumers array and hands it to
the caller, who is expected to free it at an appropriate time.
pwrseq-pcie-m2.c never did, leading to a memory leak.
Add an explicit kfree() for the consumers array.
regulator: ltc3676: don't read the write-only HRST and CLIRQ registers
In the Linux kernel, the following vulnerability has been resolved:
regulator: ltc3676: don't read the write-only HRST and CLIRQ registers
HRST (0x1e) and CLIRQ (0x1f) are write-only command strobes. Writing HRST
triggers a hard reset of the chip and writing CLIRQ clears the interrupt;
reading them returns nothing useful, and the read itself fires the command.
The result is that a plain register dump resets the b…
regulator: of: fill in supply names in of_regulator_bulk_get_all()
In the Linux kernel, the following vulnerability has been resolved:
regulator: of: fill in supply names in of_regulator_bulk_get_all()
of_regulator_bulk_get_all() returns an array it allocated itself, and
fills in only the consumer of each entry. Every other way of getting a
bulk array has the supply name set, because the caller provides it, and
the core expects it to be there: regulator_bulk_enable() prints it wh…
regulator: tps6594-regulator: Fix n_linear_ranges for TPS65224 BUCK2-4
In the Linux kernel, the following vulnerability has been resolved:
regulator: tps6594-regulator: Fix n_linear_ranges for TPS65224 BUCK2-4
The TPS65224 BUCK2, BUCK3 and BUCK4 descriptors pass 4 as
n_linear_ranges, but tps65224_bucks_2_3_4_ranges[] only has two
entries, covering selectors 0x00-0x45.
The linear range helpers loop over n_linear_ranges entries, so any
lookup of a selector above 0x45 reads past the en…
scsi: ch: Do not keep references to data transfer element devices
In the Linux kernel, the following vulnerability has been resolved:
scsi: ch: Do not keep references to data transfer element devices
ch_readconfig() looks up the scsi_device of every data transfer element
whose SCSI id the changer reports in READ ELEMENT STATUS, and stores it in
ch->dt[]. scsi_device_lookup() takes a reference, and nothing ever drops
it: ch_destroy() frees the array with kfree(). ch->dt[] is read…
riscv: entry: gate shadow call stack reload on sstatus.SPP, not tp
In the Linux kernel, the following vulnerability has been resolved:
riscv: entry: gate shadow call stack reload on sstatus.SPP, not tp
Under CONFIG_SHADOW_CALL_STACK, handle_exception() reloads the kernel
shadow call stack pointer (gp) only when the trap came from userspace.
It made that decision with scs_load_current_if_task_changed, which
compares the trap-time tp (read back from sscratch into s5) against the
cu…
riscv: errata: select RISCV_ALTERNATIVE_EARLY for THEAD GHOSTWRITE
In the Linux kernel, the following vulnerability has been resolved:
riscv: errata: select RISCV_ALTERNATIVE_EARLY for THEAD GHOSTWRITE
errata_probe_ghostwrite() only marks the CPU as vulnerable when it is
called at the RISCV_ALTERNATIVES_EARLY_BOOT stage, and the mitigation
in ghostwrite_enable_mitigation() only takes effect if the vulnerable
state was recorded before the boot alternatives are patched.
The early …
riscv: futex: untag the user pointer before the atomic access
In the Linux kernel, the following vulnerability has been resolved:
riscv: futex: untag the user pointer before the atomic access
access_ok() checks untagged_addr(uaddr), but arch_futex_atomic_op_inuser()
and futex_atomic_cmpxchg_inatomic() hand the raw uaddr to the inline asm
amoswap/amoadd/.../lr.w+sc.w through the "+m" (*uaddr) operand. When the
tagged address ABI is enabled (CONFIG_RISCV_ISA_SUPM, prctl
PR_SE…
Bluetooth: hci_sock: Serialize dead-device detachment
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_sock: Serialize dead-device detachment
Rebinding an HCI socket after its controller is unregistered can race
monitor control replay and crash the kernel. hci_sock_bind() clears
hci_pi(sk)->hdev and drops the device reference under only the socket
lock, whereas send_monitor_control_replay() holds hci_sk_list.lock for
reading.
Replay…
Bluetooth: hci_sync: Fix command skb lifetime during scan setup
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_sync: Fix command skb lifetime during scan setup
During PA sync scan setup, hci_le_set_ext_scan_param_sync() gets the
address used for the PA_LINK lookup from hci_sent_cmd_data(). The
returned pointer borrows storage from sent_cmd or req_skb, without
holding a reference to either skb.
The scan worker runs on req_workqueue while hci…
Bluetooth: ISO: Reject concurrent BIS listener setup
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: ISO: Reject concurrent BIS listener setup
iso_sock_listen() drops the socket lock before calling iso_listen_bis()
to preserve the hdev->lock ordering. Two concurrent listen() calls on
the same broadcast socket can therefore both observe BT_BOUND. Caller
A can attach connA and release the locks, then caller B can acquire
them and attach …
Bluetooth: ISO: Serialize concurrent connect calls
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: ISO: Serialize concurrent connect calls
iso_sock_connect() checks the socket state before taking the socket lock
and drops the lock again before setting up a connection. Two callers can
both pass the admission check while the socket is open or bound.
Caller A can copy its destination for route selection, then caller B can
replace the s…
Bluetooth: SCO: serialise sco_conn lifetime against sco_recv_scodata()
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: SCO: serialise sco_conn lifetime against sco_recv_scodata()
sco_recv_scodata() upgrades the weak hcon->sco_data back-pointer to a
strong reference under hdev->lock:
hci_dev_lock(hdev);
hcon = hci_conn_hash_lookup_handle(hdev, handle);
...
conn = sco_conn_hold_unless_zero(hcon->sco_data);
hci_dev_unlock(hdev);
but t…
Bluetooth: RFCOMM: free the skb when the DLC has no owner
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: RFCOMM: free the skb when the DLC has no owner
rfcomm_recv_data() hands the skb to d->data_ready() and returns 0
without freeing it, so the callback owns the skb from that point on.
The tty implementation frees it when the DLC has been detached from its
device:
static void rfcomm_dev_data_ready(struct rfcomm_dlc *dlc,
…
Bluetooth: RFCOMM: connect the session socket without rfcomm_mutex
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: RFCOMM: connect the session socket without rfcomm_mutex
An RFCOMM connect() issued while a BR/EDR link is being authenticated
makes lockdep report a circular dependency, and the reported cycle is a
real AB/BA between rfcomm_mutex and hdev->lock.
rfcomm_security_cfm() is called from the HCI event path, which already
holds hdev->lock:
…
Bluetooth: RFCOMM: Fix NULL tty_dev dereference in rfcomm_dev_shutdown
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: RFCOMM: Fix NULL tty_dev dereference in rfcomm_dev_shutdown
syzbot hit a NULL pointer dereference in rfcomm_dev_shutdown() when an
RFCOMM tty is closed.
rfcomm_dev_add() puts the new device on rfcomm_dev_list first and only
then registers the tty device and saves it in dev->tty_dev. If that
registration fails, dev->tty_dev is never set…
drm/fb-helper: defer setup when fbdev_probe() fails, not just on -EAGAIN
In the Linux kernel, the following vulnerability has been resolved:
drm/fb-helper: defer setup when fbdev_probe() fails, not just on -EAGAIN
__drm_fb_helper_initial_config_and_unlock() calls
drm_client_modeset_probe() first, which already fills in each
mode_set->mode/num_connectors for every connected output, and only
afterwards calls drm_fb_helper_single_fb_probe() to create
fb_helper->fb and wire it into those m…
drm/i915/gem: Prevent overstepping exec array boundary
In the Linux kernel, the following vulnerability has been resolved:
drm/i915/gem: Prevent overstepping exec array boundary
It is possible for eb_relocate_parse_slow() to call kvfree() on
entries outside the original exec array during following
scenario inside eb_relocate_parse_slow():
1) eb_copy_relocations() allocates as many as eb->buffer_count
copies for exec entries;
2) eb_parse() appends up to two VMAs, r…
drm/i915/gt: Unmask interrupts only when ACTIVE is true
In the Linux kernel, the following vulnerability has been resolved:
drm/i915/gt: Unmask interrupts only when ACTIVE is true
There is a small race window between intel_rps_boost() reading
a stale ACTIVE state and queuing rps->work, where ACTIVE may be
changed via asynchronous calls triggered by wakeref drop.
This means that rps_work() could be triggered after the GT has
been parked, so unmasking RPS PM interrupts w…
drm/imagination: Size page table preallocation by device address
In the Linux kernel, the following vulnerability has been resolved:
drm/imagination: Size page table preallocation by device address
Commit 0a8224058a58 ("drm/imagination: Fix page count for page table for
map() interface") passed the device address to
pvr_mmu_op_context_create(), but the preallocation is still sized from
device_addr + sgt_offset with an exclusive end. The offset into the
object's pages has no pla…
drm/panthor: validate userspace queue count against initialized firmware slot count
In the Linux kernel, the following vulnerability has been resolved:
drm/panthor: validate userspace queue count against initialized firmware slot count
In panthor_drv.c:panthor_ioctl_group_create(),
the queue count is validated against the hardcoded maximum:
if (!args->queues.count || args->queues.count > MAX_CS_PER_CSG)
return -EINVAL;
However, if the firmware reports fewer slots than MAX_CS_PER_CSG,
panthor…
drm/vmwgfx: validate pitch coming from userspace
In the Linux kernel, the following vulnerability has been resolved:
drm/vmwgfx: validate pitch coming from userspace
Validate the pitch, alongside the box dimensions before trying
to copy data from the underlying surface. Fixes possible
out of bounds reads with cursor snooping.
drm/xe/i2c: cancel the client work on remove
In the Linux kernel, the following vulnerability has been resolved:
drm/xe/i2c: cancel the client work on remove
xe_i2c_notifier() stores the DesignWare adapter in i2c->adapter and
schedules i2c->work when the adapter is registered under the xe I2C
platform device, and xe_i2c_client_work() then instantiates the AMC
client device on that adapter.
xe_i2c_remove() tears down the AMC, unregisters the client devices,
…
