CVE-2026-74576

Summary of CVE-2026-74576 (Linux kernel) : The vulnerability stems from the slab allocator allowing unbounded recursion in the free path due to cycles formed when obj_exts arrays are allocated across KMALLOC_NORMAL caches. Specifically, slabs can form a cycle by allocating each other’s obj_exts a...
