CVE-2025-68199

Mode C: The CVE-2025-68199 entry concerns the Linux kernel, where an issue in the slab allocator (mm/slub.c) arises when free_slab_obj_exts() encounters slabobj_exts already set to CODETAG_EMPTY instead of NULL. The root cause is that, after a failed then later successful alloc_slab_obj_exts(), o...
