Security Vulnerabilities - CVEs Published In February 2025
In the Linux kernel, the following vulnerability has been resolved:
soc: qcom: socinfo: Avoid out of bounds read of serial number
On MSM8916 devices, the serial number exposed in sysfs is constant and does
not change across individual devices. It's always:
db410c:/sys/devices/soc0$ cat serial_number
2644893864
The firmware used on MSM8916 exposes SOCINFO_VERSION(0, 8), which does not
have support for the serial_num field in the socinfo struct. There is an
existing check to avoid exposing the serial number in that case, but it's
not correct: When checking the item_size returned by SMEM, we need to make
sure the *end* of the serial_num is within bounds, instead of comparing
with the *start* offset. The serial_number currently exposed on MSM8916
devices is just an out of bounds read of whatever comes after the socinfo
struct in SMEM.
Fix this by changing offsetof() to offsetofend(), so that the size of the
field is also taken into account.

In the Linux kernel, the following vulnerability has been resolved:
KEYS: trusted: dcp: fix improper sg use with CONFIG_VMAP_STACK=y
With vmalloc stack addresses enabled (CONFIG_VMAP_STACK=y) DCP trusted
keys can crash during en- and decryption of the blob encryption key via
the DCP crypto driver. This is caused by improperly using sg_init_one()
with vmalloc'd stack buffers (plain_key_blob).
Fix this by always using kmalloc() for buffers we give to the DCP crypto
driver.

In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: L2CAP: handle NULL sock pointer in l2cap_sock_alloc
A NULL sock pointer is passed into l2cap_sock_alloc() when it is called
from l2cap_sock_new_connection_cb() and the error handling paths should
also be aware of it.
Seemingly a more elegant solution would be to swap bt_sock_alloc() and
l2cap_chan_create() calls since they are not interdependent to that moment
but then l2cap_chan_create() adds the soon to be deallocated and still
dummy-initialized channel to the global list accessible by many L2CAP
paths. The channel would be removed from the list in short period of time
but be a bit more straight-forward here and just check for NULL instead of
changing the order of function calls.
Found by Linux Verification Center (linuxtesting.org) with SVACE static
analysis tool.

In the Linux kernel, the following vulnerability has been resolved:
binfmt_flat: Fix integer overflow bug on 32 bit systems
Most of these sizes and counts are capped at 256MB so the math doesn't
result in an integer overflow. The "relocs" count needs to be checked
as well. Otherwise on 32bit systems the calculation of "full_data"
could be wrong.
full_data = data_len + relocs * sizeof(unsigned long);

In the Linux kernel, the following vulnerability has been resolved:
drm/xe/tracing: Fix a potential TP_printk UAF
The commit
afd2627f727b ("tracing: Check "%s" dereference via the field and not the TP_printk format")
exposes potential UAFs in the xe_bo_move trace event.
Fix those by avoiding dereferencing the
xe_mem_type_to_name[] array at TP_printk time.
Since some code refactoring has taken place, explicit backporting may
be needed for kernels older than 6.10.

In the Linux kernel, the following vulnerability has been resolved:
drm: zynqmp_dp: Fix integer overflow in zynqmp_dp_rate_get()
This patch fixes a potential integer overflow in the zynqmp_dp_rate_get()
The issue comes up when the expression
drm_dp_bw_code_to_link_rate(dp->test.bw_code) * 10000 is evaluated using 32-bit
Now the constant is a compatible 64-bit type.
Resolves coverity issues: CID 1636340 and CID 1635811

In the Linux kernel, the following vulnerability has been resolved:
drm/msm/gem: prevent integer overflow in msm_ioctl_gem_submit()
The "submit->cmd[i].size" and "submit->cmd[i].offset" variables are u32
values that come from the user via the submit_lookup_cmds() function.
This addition could lead to an integer wrapping bug so use size_add()
to prevent that.

In the Linux kernel, the following vulnerability has been resolved:
fs/ntfs3: Mark inode as bad as soon as error detected in mi_enum_attr()
Extended the `mi_enum_attr()` function interface with an additional
parameter, `struct ntfs_inode *ni`, to allow marking the inode
as bad as soon as an error is detected.

In the Linux kernel, the following vulnerability has been resolved:
NFS: Fix potential buffer overflowin nfs_sysfs_link_rpc_client()
name is char[64] where the size of clnt->cl_program->name remains
unknown. Invoking strcat() directly will also lead to potential buffer
overflow. Change them to strscpy() and strncat() to fix potential
issues.

In the Linux kernel, the following vulnerability has been resolved:
scsi: ufs: bsg: Set bsg_queue to NULL after removal
Currently, this does not cause any issues, but I believe it is necessary to
set bsg_queue to NULL after removing it to prevent potential use-after-free
(UAF) access.
