CVE-2023-53577

CVE-2023-53577 affects the Linux kernel in the bpf/cpumap path: the kthread responsible for per-CPU map updates may be stopped prematurely, leading to a warning when XDP frames/skbs remain queued in ptr_ring. The root cause is tied to the prior memory-leak fix in cpu_map_update_elem and the kthre...
