CVE-2025-71105

CVE-2025-71105 documents a Linux kernel issue in f2fs where two slab caches (f2fs_xattr_entry-7:3 and f2fs_xattr_entry-7:7) with identical slab sizes cause kmem_cache_sanity_check warnings during mount operations. The root cause is using per-sb slab caches instead of a single global slab, leading...
