CVE-2026-46093

CVE-2026-46093 affects the Linux kernel mm/vmalloc subsystem. The issue arises because decay_va_pool_node() can be invoked concurrently from two paths—the purge path and the shrinker path via vmap_node_shrink_scan—without proper serialization. This leads to races and potential memory leaks. The d...
