CVE-2026-63882 Details
Description
In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: fix NULL pointer bug in svm_range_set_attr The process_info could be NULL if user doesn't call kfd_ioctl_acquire_vm before calling kfd_ioctl_svm. (cherry picked from commit 83a26c812e0529eb040d31a76f73e33e637243d4)
A NULL pointer dereference vulnerability has been identified in the Linux kernel's AMD GPU driver (AMDKFD). This issue arises in the 'svm_range_set_attr' function, where the 'process_info' variable can be NULL if the user does not call 'kfd_ioctl_acquire_vm' before 'kfd_ioctl_svm'. This vulnerability has been addressed by adding a check to ensure 'process_info' is valid before proceeding, preventing potential crashes or undefined behavior.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been fixed. Instructions for downloading the patched version are available on the Linux Kernel Archive.
