Overview

CVE-2022-49524 is a high-severity vulnerability. It was published on February 26, 2025 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

media: pci: cx23885: Fix the error handling in cx23885_initdev()

When the driver fails to call the dma_set_mask(), the driver will get

the following splat:

[ 55.853884] BUG: KASAN: use-after-free in __process_removed_driver+0x3c/0x240

[ 55.854486] Read of size 8 at addr ffff88810de60408 by task modprobe/590

[ 55.856822] Call Trace:

[ 55.860327] __process_removed_driver+0x3c/0x240

[ 55.861347] bus_for_each_dev+0x102/0x160

[ 55.861681] i2c_del_driver+0x2f/0x50

This is because the driver has initialized the i2c related resources

in cx23885_dev_setup() but not released them in error handling, fix this

bug by modifying the error path that jumps after failing to call the

dma_set_mask().

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
