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...

CVE-2026-72496

CVE-2026-72496 affects the Linux kernel RDMA/bnxt_re path. The root cause is in bnxt_qplib_alloc_dpi returning success when ioremap fails; the fix adds proper rollback on ioremap failure and returns -ENOMEM. The published metrics indicate a CRITICAL base score (CVSS 3.1: AV:L/AC:L/PR:N/UI:N/S:C/C...

CVE-2026-72345

CVE-2026-72345 affects the Linux kernel mlx5 LAG handling. The vulnerability arises in the single-FDB error rollback: on failure at index i, the reverse cleanup loop in mlx5_lag_create_single_fdb() starts from i, risking rollback of the failed index or double-tearing down a rule already self-roll...

CVE-2026-72307

CVE-2026-72307 describes a Linux kernel issue in the mlxsw path where, after replacing VRs, the error rollback loop failed to update the vr pointer, causing a refcount leak of new_tree if replacements were partially completed. The root cause: the loop variable could point at the wrong VR, causing...
