CVSS v3.1 |
| Netis ADSL Router DL4322D firmware RTK 2.1.1 contains a buffer overflow vulnerability in the embedded FTP service that allows an authenticated remote user to trigger a denial of service. After logging in to the FTP service, sending an FTP command such as ABOR with an excessively long argument causes the service, and in practice the router, to crash or become unresponsive, resulting in a loss of availability for the device and connected users. |
| Ubee EVW3226 cable modem/routers firmware versions up to and including 1.0.20 store configuration backup files in the web root after they are generated for download. These backup files remain accessible without authentication until the next reboot. A remote attacker on the local network can request 'Configuration_file.cfg' directly to obtain the backup archive. Because backup files are not encrypted, they expose sensitive information including the plaintext admin password, allowing full compromise of the device. |
| The verify function in Encryption/Symmetric.php in Malcolm Fell jwt before 1.0.3 does not use a timing-safe function for hash comparison, which allows attackers to spoof signatures via a timing attack. |
| Early versions of Operator-SDK provided an insecure method to allow operator containers to run in environments that used a random UID. Operator-SDK before 0.15.2 provided a script, user_setup, which modifies the permissions of the /etc/passwd file to 664 during build time. Developers who used Operator-SDK before 0.15.2 to scaffold their operator may still be impacted by this if the insecure user_setup script is still being used to build new container images.
In affected images, the /etc/passwd file is created during build time with group-writable permissions and a group ownership of root (gid=0). An attacker who can execute commands within an affected container, even as a non-root user, may be able to leverage their membership in the root group to modify the /etc/passwd file. This could allow the attacker to add a new user with any arbitrary UID, including UID 0, leading to full root privileges within the container. |
| A flaw has been found in SourceCodester Train Station Ticketing System 1.0. This vulnerability affects unknown code of the file /ajax.php?action=save_user. Executing manipulation of the argument Username can lead to sql injection. The attack may be launched remotely. The exploit has been published and may be used. |
| In the Linux kernel, the following vulnerability has been resolved:
ASoC: Intel: avs: Verify content returned by parse_int_array()
The first element of the returned array stores its length. If it is 0,
any manipulation beyond the element at index 0 ends with null-ptr-deref. |
| In the Linux kernel, the following vulnerability has been resolved:
ASoC: Intel: avs: Fix possible null-ptr-deref when initing hw
Search result of avs_dai_find_path_template() shall be verified before
being used. As 'template' is already known when
avs_hw_constraints_init() is fired, drop the search entirely. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/xe/vm: move xe_svm_init() earlier
In xe_vm_close_and_put() we need to be able to call xe_svm_fini(),
however during vm creation we can call this on the error path, before
having actually initialised the svm state, leading to various splats
followed by a fatal NPD.

| In the Linux kernel, the following vulnerability has been resolved:
iavf: get rid of the crit lock
Get rid of the crit lock.
That frees us from the error prone logic of try_locks.
Thanks to netdev_lock() by Jakub it is now easy, and in most cases we were
protected by it already - replace crit lock by netdev lock when it was not
the case.
Lockdep reports that we should cancel the work under crit_lock [splat1],
and that was the scheme we have mostly followed since [1] by Slawomir.
But when that is done we still got into deadlocks [splat2]. So instead
we should look at the bigger problem, namely "weird locking/scheduling"
of the iavf. The first step to fix that is to remove the crit lock.
I will followup with a -next series that simplifies scheduling/tasks.
Cancel the work without netdev lock (weird unlock+lock scheme),
to fix the [splat2] (which would be totally ugly if we would kept
the crit lock).
Extend protected part of iavf_watchdog_task() to include scheduling
more work.
Note that the removed comment in iavf_reset_task() was misplaced,
it belonged to inside of the removed if condition, so it's gone now.
[splat1] - w/o this patch - The deadlock during VF removal:

| In the Linux kernel, the following vulnerability has been resolved:
virtio-pci: Fix result size returned for the admin command completion
The result size returned by virtio_pci_admin_dev_parts_get() is 8 bytes
larger than the actual result data size. This occurs because the
result_sg_size field of the command is filled with the result length
from virtqueue_get_buf(), which includes both the data size and an
additional 8 bytes of status.
This oversized result size causes two issues:
1. The state transferred to the destination includes 8 bytes of extra
data at the end.
2. The allocated buffer in the kernel may be smaller than the returned
size, leading to failures when reading beyond the allocated size.
The commit fixes this by subtracting the status size from the result of
virtqueue_get_buf().
This fix has been tested through live migrations with virtio-net,
virtio-net-transitional, and virtio-blk devices. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: btintel: Check dsbr size from EFI variable
Since the size of struct btintel_dsbr is already known, we can just
start there instead of querying the EFI variable size. If the final
result doesn't match what we expect also fail. This fixes a stack buffer
overflow when the EFI variable is larger than struct btintel_dsbr. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7996: avoid NULL pointer dereference in mt7996_set_monitor()
The function mt7996_set_monitor() dereferences phy before
the NULL sanity check.
Fix this to avoid NULL pointer dereference by moving the
dereference after the check. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: Fix buffer overflow in debugfs
If the user tries to write more than 32 bytes then it results in memory
corruption. Fortunately, this is debugfs so it's limited to root users. |
| In the Linux kernel, the following vulnerability has been resolved:
perf: arm-ni: Fix missing platform_set_drvdata()
Add missing platform_set_drvdata in arm_ni_probe(), otherwise
calling platform_get_drvdata() in remove returns NULL. |
| In the Linux kernel, the following vulnerability has been resolved:
smb: Log an error when close_all_cached_dirs fails
Under low-memory conditions, close_all_cached_dirs() can't move the
dentries to a separate list to dput() them once the locks are dropped.
This will result in a "Dentry still in use" error, so add an error
message that makes it clear this is what happened:
[ 495.281119] CIFS: VFS: \\otters.example.com\share Out of memory while dropping dentries
[ 495.281595] ------------[ cut here ]------------
[ 495.281887] BUG: Dentry ffff888115531138{i=78,n=/} still in use (2) [unmount of cifs cifs]
[ 495.282391] WARNING: CPU: 1 PID: 2329 at fs/dcache.c:1536 umount_check+0xc8/0xf0
Also, bail out of looping through all tcons as soon as a single
allocation fails, since we're already in trouble, and kmalloc() attempts
for subseqeuent tcons are likely to fail just like the first one did. |
| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: add free_transport ops in ksmbd connection
free_transport function for tcp connection can be called from smbdirect.
It will cause kernel oops. This patch add free_transport ops in ksmbd
connection, and add each free_transports for tcp and smbdirect. |
| In the Linux kernel, the following vulnerability has been resolved:
fgraph: Do not enable function_graph tracer when setting funcgraph-args
When setting the funcgraph-args option when function graph tracer is net
enabled, it incorrectly enables it. Worse, it unregisters itself when it
was never registered. Then when it gets enabled again, it will register
itself a second time causing a WARNing.

Notice the "tracer: nop" at the top there. The current tracer is the "nop"
tracer, but the content is obviously the function graph tracer.
Enabling function graph tracing will cause it to register again and
trigger a warning in the accounting:

| In the Linux kernel, the following vulnerability has been resolved:
firmware: cs_dsp: Fix OOB memory read access in KUnit test (wmfw info)
KASAN reported out of bounds access - cs_dsp_mock_wmfw_add_info(),
because the source string length was rounded up to the allocation size. |
| In the Linux kernel, the following vulnerability has been resolved:
firmware: cs_dsp: Fix OOB memory read access in KUnit test (ctl cache)
KASAN reported out of bounds access - cs_dsp_ctl_cache_init_multiple_offsets().
The code uses mock_coeff_template.length_bytes (4 bytes) for register value
allocations. But later, this length is set to 8 bytes which causes
test code failures.
As fix, just remove the lenght override, keeping the original value 4
for all operations. |
