CVE-2026-74382

CVE-2026-74382 concerns a stack overflow in the Linux kernel’s net/sched cls_bpf offload rollback. The issue arises when cls_bpf_offload_cmd() recursively re-enters during rollback if tc_setup_cb_replace() fails twice in a row, allowing unbounded recursion until the stack is exhausted. Two propos...
