A race condition in the Linux kernel's KASAN (Kernel Address Sanitizer) cache shrink mechanism during CPU hotplug operations can cause objects to remain on per-CPU shrink lists. This prevents proper release of slab cache objects, potentially causing memory to not be freed correctly. The issue was observed with the virtio-9p filesystem where unmount operations left objects in the cache, leading to kernel warnings about objects remaining on cache shutdown.
