CVE-2026-45876

CVE-2026-45876 affects the Linux kernel (arm64 architecture) in the arch_set_shadow_stack_status flow. The bug arises from error handling in alloc_gcs(), which can return an error-encoded pointer from do_mmap() instead of NULL. A NULL-based check fails to detect these errors, risking use of an in...
