CVSS v3.1 |
| Insufficient control flow management in the Linux kernel-mode driver for some Intel(R) 800 Series Ethernet before version 1.17.2 may allow an authenticated user to potentially enable escalation of privilege via local access. |
| In the Linux kernel, the following vulnerability has been resolved:
pinctrl: thunderbay: fix possible memory leak in thunderbay_build_functions()
The thunderbay_add_functions() will free memory of thunderbay_funcs
when everything is ok, but thunderbay_funcs will not be freed when
thunderbay_add_functions() fails, then there will be a memory leak,
so we need to add kfree() when thunderbay_add_functions() fails to
fix it.
In addition, doing some cleaner works, moving kfree(funcs) from
thunderbay_add_functions() to thunderbay_build_functions(). |
| In the Linux kernel, the following vulnerability has been resolved:
iio: fix memory leak in iio_device_register_eventset()
When iio_device_register_sysfs_group() returns failed,
iio_device_register_eventset() needs to free attrs array.
Otherwise, kmemleak would scan & report memory leak as below:
unreferenced object 0xffff88810a1cc3c0 (size 32):
comm "100-i2c-vcnl302", pid 728, jiffies 4295052307 (age 156.027s)

| In the Linux kernel, the following vulnerability has been resolved:
tpm: acpi: Call acpi_put_table() to fix memory leak
The start and length of the event log area are obtained from
TPM2 or TCPA table, so we call acpi_get_table() to get the
ACPI information, but the acpi_get_table() should be coupled with
acpi_put_table() to release the ACPI memory, add the acpi_put_table()
properly to fix the memory leak.
While we are at it, remove the redundant empty line at the
end of the tpm_read_log_acpi(). |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: plfxlc: fix potential memory leak in __lf_x_usb_enable_rx()
urbs does not be freed in exception paths in __lf_x_usb_enable_rx().
That will trigger memory leak. To fix it, add kfree() for urbs within
"error" label. Compile tested only. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: f_hid: fix f_hidg lifetime vs cdev
The embedded struct cdev does not have its lifetime correctly tied to
the enclosing struct f_hidg, so there is a use-after-free if /dev/hidgN
is held open while the gadget is deleted.
This can readily be replicated with libusbgx's example programs (for
conciseness - operating directly via configfs is equivalent):
gadget-hid
exec 3<> /dev/hidg0
gadget-vid-pid-remove
exec 3<&-
Pull the existing device up in to struct f_hidg and make use of the
cdev_device_{add,del}() helpers. This changes the lifetime of the
device object to match struct f_hidg, but note that it is still added
and deleted at the same time. |
| In the Linux kernel, the following vulnerability has been resolved:
ASoC: audio-graph-card: fix refcount leak of cpu_ep in __graph_for_each_link()
The of_get_next_child() returns a node with refcount incremented, and
decrements the refcount of prev. So in the error path of the while loop,
of_node_put() needs be called for cpu_ep. |
| In the Linux kernel, the following vulnerability has been resolved:
NFSv4/pNFS: Clear NFS_INO_LAYOUTCOMMIT in pnfs_mark_layout_stateid_invalid
Fixes a crash when layout is null during this call stack:
write_inode
-> nfs4_write_inode
-> pnfs_layoutcommit_inode
pnfs_set_layoutcommit relies on the lseg refcount to keep the layout
around. Need to clear NFS_INO_LAYOUTCOMMIT otherwise we might attempt
to reference a null layout. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/panthor: Fix UAF race between device unplug and FW event processing
The function panthor_fw_unplug() will free the FW memory sections.
The problem is that there could still be pending FW events which are yet
not handled at this point. process_fw_events_work() can in this case try
to access said freed memory.
Simply call disable_work_sync() to both drain and prevent future
invocation of process_fw_events_work(). |
| In the Linux kernel, the following vulnerability has been resolved:
nouveau/firmware: Add missing kfree() of nvkm_falcon_fw::boot
nvkm_falcon_fw::boot is allocated, but no one frees it. This causes a
kmemleak warning.
Make sure this data is deallocated. |
| In the Linux kernel, the following vulnerability has been resolved:
pid: Add a judgment for ns null in pid_nr_ns
__task_pid_nr_ns
ns = task_active_pid_ns(current);
pid_nr_ns(rcu_dereference(*task_pid_ptr(task, type)), ns);
if (pid && ns->level <= pid->level) {
Sometimes null is returned for task_active_pid_ns. Then it will trigger kernel panic in pid_nr_ns.

Kernel panic - not syncing: Oops: Fatal exception in interrupt |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: hide VRAM sysfs attributes on GPUs without VRAM
Otherwise accessing them can cause a crash. |
| In the Linux kernel, the following vulnerability has been resolved:
crypto: hisilicon/qm - set NULL to qm->debug.qm_diff_regs
When the initialization of qm->debug.acc_diff_reg fails,
the probe process does not exit. However, after qm->debug.qm_diff_regs is
freed, it is not set to NULL. This can lead to a double free when the
remove process attempts to free it again. Therefore, qm->debug.qm_diff_regs
should be set to NULL after it is freed. |

The panic was caused by UAF issue w/ below race condition:
kworker
- writepages
- f2fs_write_cache_pages
- f2fs_write_single_data_page
- f2fs_do_write_data_page
- f2fs_inplace_write_data
- f2fs_merge_page_bio
- add_inu_page

- add_inu_page
: cache page #2 into bio which is linked
in io->bio_list
write
- f2fs_write_begin
: write page #1
- f2fs_folio_wait_writeback
- f2fs_submit_merged_ipu_write
- f2fs_submit_write_bio
: submit bio which inclues page #1 and #2
software IRQ
- f2fs_write_end_io
- fscrypt_free_bounce_page
: freed bounced page which belongs to page #2
- inc_page_count( , WB_DATA_TYPE(data_folio), false)
: data_folio points to fio->encrypted_page
the bounced page can be freed before
accessing it in f2fs_is_cp_guarantee()
It can reproduce w/ below testcase:
Run below script in shell #1:
for ((i=1;i>0;i++)) do xfs_io -f /mnt/f2fs/enc/file \
-c "pwrite 0 32k" -c "fdatasync"
Run below script in shell #2:
for ((i=1;i>0;i++)) do xfs_io -f /mnt/f2fs/enc/file \
-c "pwrite 0 32k" -c "fdatasync"
So, in f2fs_merge_page_bio(), let's avoid using fio->encrypted_page after
commit page into internal ipu cache. |
| In the Linux kernel, the following vulnerability has been resolved:
smb: client: fix crypto buffers in non-linear memory
The crypto API, through the scatterlist API, expects input buffers to be
in linear memory. We handle this with the cifs_sg_set_buf() helper
that converts vmalloc'd memory to their corresponding pages.
However, when we allocate our aead_request buffer (@creq in
smb2ops.c::crypt_message()), we do so with kvzalloc(), which possibly
puts aead_request->__ctx in vmalloc area.
AEAD algorithm then uses ->__ctx for its private/internal data and
operations, and uses sg_set_buf() for such data on a few places.
This works fine as long as @creq falls into kmalloc zone (small
requests) or vmalloc'd memory is still within linear range.
Tasks' stacks are vmalloc'd by default (CONFIG_VMAP_STACK=y), so too
many tasks will increment the base stacks' addresses to a point where
virt_addr_valid(buf) will fail (BUG() in sg_set_buf()) when that
happens.
In practice: too many parallel reads and writes on an encrypted mount
will trigger this bug.
To fix this, always alloc @creq with kmalloc() instead.
Also drop the @sensitive_size variable/arguments since
kfree_sensitive() doesn't need it.

mm/damon/core: fix potential memory leak by cleaning ops_filter in damon_destroy_scheme
Currently, damon_destroy_scheme() only cleans up the filter list but
leaves ops_filter untouched, which could lead to memory leaks when a
scheme is destroyed.
This patch ensures both filter and ops_filter are properly freed in
damon_destroy_scheme(), preventing potential memory leaks. |
| In the Linux kernel, the following vulnerability has been resolved:
tcp: Don't call reqsk_fastopen_remove() in tcp_conn_request().
syzbot reported the splat below in tcp_conn_request(). [0]
If a listener is close()d while a TFO socket is being processed in
tcp_conn_request(), inet_csk_reqsk_queue_add() does not set reqsk->sk
and calls inet_child_forget(), which calls tcp_disconnect() for the
TFO socket.
After the cited commit, tcp_disconnect() calls reqsk_fastopen_remove(),
where reqsk_put() is called due to !reqsk->sk.
Then, reqsk_fastopen_remove() in tcp_conn_request() decrements the
last req->rsk_refcnt and frees reqsk, and __reqsk_free() at the
drop_and_free label causes the refcount underflow for the listener
and double-free of the reqsk.
Let's remove reqsk_fastopen_remove() in tcp_conn_request().
Note that other callers make sure tp->fastopen_rsk is not NULL.

refcount_t: underflow; use-after-free.

pwm: berlin: Fix wrong register in suspend/resume
The 'enable' register should be BERLIN_PWM_EN rather than
BERLIN_PWM_ENABLE, otherwise, the driver accesses wrong address, there
will be cpu exception then kernel panic during suspend/resume. |
| In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: Clean up only new IRQ glue on request_irq() failure
The mlx5_irq_alloc() function can inadvertently free the entire rmap
and end up in a crash[1] when the other threads tries to access this,
when request_irq() fails due to exhausted IRQ vectors. This commit
modifies the cleanup to remove only the specific IRQ mapping that was
just added.
This prevents removal of other valid mappings and ensures precise
cleanup of the failed IRQ allocation's associated glue object.
Note: This error is observed when both fwctl and rds configs are enabled.

| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: MGMT: fix crash in set_mesh_sync and set_mesh_complete
There is a BUG: KASAN: stack-out-of-bounds in set_mesh_sync due to
memcpy from badly declared on-stack flexible array.
Another crash is in set_mesh_complete() due to double list_del via
mgmt_pending_valid + mgmt_pending_remove.
Use DEFINE_FLEX to declare the flexible array right, and don't memcpy
outside bounds.
As mgmt_pending_valid removes the cmd from list, use mgmt_pending_free,
and also report status on error. |
