Security Vulnerabilities - CVEs Published In November 2024
In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Ensure DA_ID handling completion before deleting an NPIV instance
Deleting an NPIV instance requires all fabric ndlps to be released before
an NPIV's resources can be torn down. Failure to release fabric ndlps
beforehand opens kref imbalance race conditions. Fix by forcing the DA_ID
to complete synchronously with usage of wait_queue.

In the Linux kernel, the following vulnerability has been resolved:
virtio_pmem: Check device status before requesting flush
If a pmem device is in a bad status, the driver side could wait for
host ack forever in virtio_pmem_flush(), causing the system to hang.
So add a status check in the beginning of virtio_pmem_flush() to return
early if the device is not activated.

In the Linux kernel, the following vulnerability has been resolved:
mptcp: handle consistently DSS corruption
Bugged peer implementation can send corrupted DSS options, consistently
hitting a few warning in the data path. Use DEBUG_NET assertions, to
avoid the splat on some builds and handle consistently the error, dumping
related MIBs and performing fallback and/or reset according to the
subflow type.

In the Linux kernel, the following vulnerability has been resolved:
net: explicitly clear the sk pointer, when pf->create fails
We have recently noticed the exact same KASAN splat as in commit
6cd4a78d962b ("net: do not leave a dangling sk pointer, when socket
creation fails"). The problem is that commit did not fully address the
problem, as some pf->create implementations do not use sk_common_release
in their error paths.
For example, we can use the same reproducer as in the above commit, but
changing ping to arping. arping uses AF_PACKET socket and if packet_create
fails, it will just sk_free the allocated sk object.
While we could chase all the pf->create implementations and make sure they
NULL the freed sk object on error from the socket, we can't guarantee
future protocols will not make the same mistake.
So it is easier to just explicitly NULL the sk pointer upon return from
pf->create in __sock_create. We do know that pf->create always releases the
allocated sk object on error, so if the pointer is not NULL, it is
definitely dangling.

In the Linux kernel, the following vulnerability has been resolved:
drm/vc4: Stop the active perfmon before being destroyed
Upon closing the file descriptor, the active performance monitor is not
stopped. Although all perfmons are destroyed in `vc4_perfmon_close_file()`,
the active performance monitor's pointer (`vc4->active_perfmon`) is still
retained.
If we open a new file descriptor and submit a few jobs with performance
monitors, the driver will attempt to stop the active performance monitor
using the stale pointer in `vc4->active_perfmon`. However, this pointer
is no longer valid because the previous process has already terminated,
and all performance monitors associated with it have been destroyed and
freed.
To fix this, when the active performance monitor belongs to a given
process, explicitly stop it before destroying and freeing it.

In the Linux kernel, the following vulnerability has been resolved:
net: phy: dp83869: fix memory corruption when enabling fiber
When configuring the fiber port, the DP83869 PHY driver incorrectly
calls linkmode_set_bit() with a bit mask (1 << 10) rather than a bit
number (10). This corrupts some other memory location -- in case of
arm64 the priv pointer in the same structure.
Since the advertising flags are updated from supported at the end of the
function the incorrect line isn't needed at all and can be removed.

In the Linux kernel, the following vulnerability has been resolved:
HID: amd_sfh: Switch to device-managed dmam_alloc_coherent()
Using the device-managed version allows to simplify clean-up in probe()
error path.
Additionally, this device-managed ensures proper cleanup, which helps to
resolve memory errors, page faults, btrfs going read-only, and btrfs
disk corruption.

In the Linux kernel, the following vulnerability has been resolved:
ice: fix memleak in ice_init_tx_topology()
Fix leak of the FW blob (DDP pkg).
Make ice_cfg_tx_topo() const-correct, so ice_init_tx_topology() can avoid
copying whole FW blob. Copy just the topology section, and only when
needed. Reuse the buffer allocated for the read of the current topology.
This was found by kmemleak, with the following trace for each PF:
[<ffffffff8761044d>] kmemdup_noprof+0x1d/0x50
[<ffffffffc0a0a480>] ice_init_ddp_config+0x100/0x220 [ice]
[<ffffffffc0a0da7f>] ice_init_dev+0x6f/0x200 [ice]
[<ffffffffc0a0dc49>] ice_init+0x29/0x560 [ice]
[<ffffffffc0a10c1d>] ice_probe+0x21d/0x310 [ice]
Constify ice_cfg_tx_topo() @buf parameter.
This cascades further down to few more functions.
