CVE-2024-53172 addresses a vulnerability in the Linux kernel's UBI fastmap feature where duplicate slab cache names are created during the fast attaching process. This triggers kernel warnings and can lead to a denial of service condition. The issue occurs because the alloc_ai() function is called twice with the same slab cache name 'ubi_aeb_slab_cache' when CONFIG_DEBUG_VM=y is enabled. The vulnerability has been fixed by assigning different slab cache names to the alloc_ai() callers.
