CVE-2025-71124

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/msm/a6xx: move preempt_prepare_postamble after error check<br /> <br /> Move the call to preempt_prepare_postamble() after verifying that<br /> preempt_postamble_ptr is valid. If preempt_postamble_ptr is NULL,<br /> dereferencing it in preempt_prepare_postamble() would lead to a crash.<br /> <br /> This change avoids calling the preparation function when the<br /> postamble allocation has failed, preventing potential NULL pointer<br /> dereference and ensuring proper error handling.<br /> <br /> Patchwork: https://patchwork.freedesktop.org/patch/687659/
