gpio: mpsse: fix race when arming the IRQ poll worker
In the Linux kernel, the following vulnerability has been resolved:
gpio: mpsse: fix race when arming the IRQ poll worker
gpio_mpsse_irq_enable() arms the poll worker before publishing it:
schedule_work() runs before the worker is added to priv->workers. If
gpio_mpsse_disconnect() walks the list in that window it misses the
worker, and once disconnect returns, the USB core frees mpsse_priv
while the orphaned gpio_…
gpio: xilinx: fix runtime PM leak on request error path
In the Linux kernel, the following vulnerability has been resolved:
gpio: xilinx: fix runtime PM leak on request error path
pm_runtime_get_sync() leaves the usage counter incremented even when it
fails, and xgpio_request() returns the error without dropping it.
gpiolib does not call ->free() when ->request() fails, so xgpio_free(),
which holds the only matching pm_runtime_put(), never runs. The reference
is leake…
gve: fix napi_disable deadlock when attempting to disable XSK pools
In the Linux kernel, the following vulnerability has been resolved:
gve: fix napi_disable deadlock when attempting to disable XSK pools
When disabling XSK pools, GVE calls the unlocked versions of
napi_disable and napi_enable. However, the netdev lock has already been
acquired before ndo_bpf is called because GVE supports queue management
ops. Calling the unlocked versions of napi_disable/enable results in a
deadl…
gve: fix XSK buffer leak when rings are stopped
In the Linux kernel, the following vulnerability has been resolved:
gve: fix XSK buffer leak when rings are stopped
GVE does not free XSK buffers when resetting ring state as a part of
stopping queues. This causes all XSK buffers which are posted to the
NIC to be leaked.
Free XSK buffers attached to an allocated buf_state when stopping rings.
This issue was hit in production.
gve: fix XSK buffer leak on error descriptor
In the Linux kernel, the following vulnerability has been resolved:
gve: fix XSK buffer leak on error descriptor
When the error bit is set in the RX completion descriptor, the buf_state
and its attached buffer should be freed. In the case of AF_XDP ZC, the
XSK buffer was not freed, leading to a leak.
This issue was caught by LLM.
ibmveth: h_free logical LAN on open-fail after register
In the Linux kernel, the following vulnerability has been resolved:
ibmveth: h_free logical LAN on open-fail after register
ibmveth_open() registers the logical LAN, then allocates the RX
buffer pools. A pool failure jumps to out_free_buffer_pools without
h_free_logical_lan(), so PHYP still owns the buffer-list page when
it is unmapped. request_irq() failure already issued the hypercall
before taking the same labe…
ice: fix use-after-free in dynamic port cleanup
In the Linux kernel, the following vulnerability has been resolved:
ice: fix use-after-free in dynamic port cleanup
ice_dealloc_dynamic_port() uses dyn_port->vsi->idx to erase the dynamic
port from pf->dyn_ports. However, it frees the VSI before reading the
index for the erase, resulting in a use-after-free.
Follow the reverse of the allocation order in ice_alloc_dynamic_port()
by erasing the xarray entry before …
ice: fix metadata_dst refcount handling on representor teardown
In the Linux kernel, the following vulnerability has been resolved:
ice: fix metadata_dst refcount handling on representor teardown
ice_eswitch_release_repr() uses metadata_dst_free() to release the
representor's metadata_dst. metadata_dst_free() directly frees the
underlying memory without checking the dst_entry refcount.
When ice_eswitch_port_start_xmit() processes a packet, it takes a
reference via dst_hold()…
io_uring/net: populate CONNECT filter fields for 24-byte sockaddr_in6
In the Linux kernel, the following vulnerability has been resolved:
io_uring/net: populate CONNECT filter fields for 24-byte sockaddr_in6
io_connect_bpf_populate() fills connect.port and connect.v6_addr for
AF_INET6 only when addr_len >= sizeof(struct sockaddr_in6), i.e. 28
bytes.
The IPv6 connect paths accept SIN6_LEN_RFC2133 (24 bytes), which
already holds sin6_port and sin6_addr. io_connect() passes addr_len t…
ip6_gre: remove obsolete ERSPAN PMTU update
In the Linux kernel, the following vulnerability has been resolved:
ip6_gre: remove obsolete ERSPAN PMTU update
A tc tunnel_key action can attach a METADATA_IP_TUNNEL dst to an skb,
and mirred can redirect it to a native ip6erspan device. The legacy PMTU
update in ip6erspan_tunnel_xmit() treats that metadata dst as a route.
Since it has no output device, dst_dev(dst)->mtu dereferences NULL.
On v7.2 with KASAN, an…
KEYS: Fix add_key() race with keyring restriction
In the Linux kernel, the following vulnerability has been resolved:
KEYS: Fix add_key() race with keyring restriction
__key_create_or_update() snapshots keyring->restrict_link before taking
the destination keyring's semaphore. keyring_restrict() installs a
restriction while holding that semaphore.
This allows a writer to observe no restriction, wait for the keyring
owner to install a reject-all restriction and r…
memstick: core: wait for request completion before freeing card
In the Linux kernel, the following vulnerability has been resolved:
memstick: core: wait for request completion before freeing card
In memstick_alloc_card() and memstick_set_rw_addr(),
wait_for_completion_timeout() is used to wait for device identification
and address configuration requests to complete.
The memstick subsystem does not provide an abort or cancellation
callback in struct memstick_host for in-flight…
memstick: rtsx_usb_ms: complete requests after eject instead of dropping them
In the Linux kernel, the following vulnerability has been resolved:
memstick: rtsx_usb_ms: complete requests after eject instead of dropping them
memstick_check() can pass its host->removing check just before
rtsx_usb_ms_drv_remove() sets eject/removing. Its next request is then
silently dropped: rtsx_usb_ms_request() skips schedule_work() once eject
is set, and drv_remove's cancel_work_sync() can also cancel a qu…
dm-crypt: reject the lmk IV mode with AEAD ciphers
In the Linux kernel, the following vulnerability has been resolved:
dm-crypt: reject the lmk IV mode with AEAD ciphers
A "capi:" table line that pairs an AEAD cipher with the lmk IV mode,
for example "capi:gcm(aes)-lmk" with the integrity:28:aead option,
causes an oops when it is loaded. lmk sets tfms_count to 64, but
crypt_alloc_tfms_aead only allocates one transform, so crypt_setkey
reads past the end of the tfm…
dm: fix reading free memory in do_resume
In the Linux kernel, the following vulnerability has been resolved:
dm: fix reading free memory in do_resume
When do_resume calls dm_table_get_mode(new_map), the call is done without
holding any locks (it only holds a reference to the md). It may be
possible that another concurrent ioctl on the same device will swap table
after dm_swap_table and before dm_table_get_mode. In this case,
dm_table_get_mode(new_map) re…
mmc: mtk-sd: Cancel request timeout work on remove
In the Linux kernel, the following vulnerability has been resolved:
mmc: mtk-sd: Cancel request timeout work on remove
The driver queues req_timeout while a request is active.
msdc_request_done() uses cancel_delayed_work(), which does not wait for
a timeout callback that has already started.
The timeout callback calls mmc_request_done(), which wakes the request
waiter, and then continues to use host->dev_comp and…
mmc: sdhci-sprd: disable runtime PM on remove
In the Linux kernel, the following vulnerability has been resolved:
mmc: sdhci-sprd: disable runtime PM on remove
sdhci_sprd_probe() enables runtime PM, while sdhci_sprd_remove() does
not perform the corresponding runtime PM cleanup.
The probe failure path disables runtime PM before disabling the clocks,
but the normal remove path directly disables clocks that are also
managed by the runtime PM callbacks. If the …
net/packet: guard the ll header push in packet_rcv_spkt()
In the Linux kernel, the following vulnerability has been resolved:
net/packet: guard the ll header push in packet_rcv_spkt()
packet_rcv_spkt() restores the link layer header with
skb_push(skb, skb->data - skb_mac_header(skb));
That subtraction is only meaningful when the device actually has a link
layer header. packet_rcv() and tpacket_rcv() both wrap it in
dev_has_header(), which is also the predicate the bl…
net/smc: protect clcsock lifetime in smc_getname
In the Linux kernel, the following vulnerability has been resolved:
net/smc: protect clcsock lifetime in smc_getname
smc_getname() dereferences smc->clcsock without holding
clcsock_release_lock. Link-group termination can release the CLC socket
through smc_close_active_abort() while the SMC socket is still open,
for example after shutdown(SHUT_WR).
A getsockname() caller can load smc->clcsock, then the terminatio…
net: bridge: avoid recursive multicast port cleanup
In the Linux kernel, the following vulnerability has been resolved:
net: bridge: avoid recursive multicast port cleanup
br_multicast_sg_del_exclude_ports() removes automatically added STAR_EXCL
port groups by calling br_multicast_del_pg(). For S,G entries, that
deletion calls back into br_multicast_sg_del_exclude_ports(), so a large
number of STAR_EXCL ports consumes one kernel stack frame per port and can
hit the…
net: skbuff: don't leave stale bytes in skb_copy_and_csum_bits()
In the Linux kernel, the following vulnerability has been resolved:
net: skbuff: don't leave stale bytes in skb_copy_and_csum_bits()
When skb_copy_and_csum_bits() reaches unreadable frags it returns 0
after copying only the linear part, and the rest of the caller's buffer
is left as it was. The callers copy into a buffer that is about to go
out on the wire: an ICMP error quoting the offending packet, or a
driver'…
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…
