AI-suggested
A fix is available that removes the redundant manual freeing of pdata after auxiliary device initialization. Users should update to patched versions of the linux-hwe-edge kernel to remediate this issue. No additional mitigation steps are indicated by the vendor advisory.
Description
A use-after-free vulnerability in the Linux kernel's media subsystem (ipu6 driver) was resolved by removing redundant frees of auxiliary device pdata after initialization. The issue could lead to double-free scenarios during error unwinding in device initialization. This vulnerability affects specific versions of the linux-hwe-edge kernel and has a CVSS score of 7.8.
