CVE-2026-63879 affects the Linux kernel AMDGPU driver's amdgpu_hmm_range_get_pages function. Reading the notifier sequence more than once can cause the page-handling logic to operate on invalid pages. The fix reads the notifier sequence only once, preventing inconsistent sequence handling. Invalid page use can potentially cause memory-safety issues or kernel instability; specific attacker-controlled exploitation outcomes have not been established.
