CVE-2025-71124 Details
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. Patchwork: https://patchwork.freedesktop.org/patch/687659/
A vulnerability in the Linux kernel's DRM MSM A6XX graphics driver can lead to a NULL pointer dereference. This issue occurs because the function 'preempt_prepare_postamble' was called before checking if 'preempt_postamble_ptr' was valid. If 'preempt_postamble_ptr' is NULL, dereferencing it would cause a crash. The vulnerability affects the stable versions of the Linux kernel.
