CVE-2025-71124

MEDIUM

Linux Kernel 6.13-6.18.2 - NULL Pointer Dereference in DRM MSM A6XX Preempt Postamble

Title source: llm
STIX 2.1

Description

In the Linux kernel, the following vulnerability has been resolved: drm/msm/a6xx: move preempt_prepare_postamble after error check Move the call to preempt_prepare_postamble() after verifying that preempt_postamble_ptr is valid. If preempt_postamble_ptr is NULL, dereferencing it in preempt_prepare_postamble() would lead to a crash. This change avoids calling the preparation function when the postamble allocation has failed, preventing potential NULL pointer dereference and ensuring proper error handling.
