Loading vulnerability…
CVE-2024-36883 is a race condition in the Linux kernel networking subsystem's generic network-namespace allocation path. net_alloc_generic reads max_gen_ptrs twice without locking: once when allocating a variable-length array and again when setting the array length used to bound later access. Concurrent registration of a new per-network-namespace operation can increase max_gen_ptrs between those reads, causing the recorded length to exceed the allocated array size and enabling an out-of-bounds access. The upstream correction reads max_gen_ptrs once in net_alloc_generic; a later increment is handled by net_assign_generic.
