In the Linux kernel, the following vulnerability has been resolved:
mm/vmalloc: take vmap_purge_lock in shrinker
decay_va_pool_node() can be invoked concurrently from two paths: __purge_vmap_area_lazy() when pools are being purged, and the shrinker via vmap_node_shrink_scan().
However, decay_va_pool_node() is not safe to run concurrently, and the shrinker path currently lacks serialization, leading to races and possible leaks.
Protect decay_va_pool_node() by taking vmap_purge_lock in the shrinker path to ensure serialization with purge users.
