GHSA-CV3R-FFC6-6HCP

Vulnerability from github – Published: 2025-09-11 18:35 – Updated: 2025-11-25 18:32

Details

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

drm/msm: Add error handling for krealloc in metadata setup

Function msm_ioctl_gem_info_set_metadata() now checks for krealloc failure and returns -ENOMEM, avoiding potential NULL pointer dereference. Explicitly avoids __GFP_NOFAIL due to deadlock risks and allocation constraints.

Patchwork: https://patchwork.freedesktop.org/patch/661235/

Severity ?

5.5 (Medium)
