CVE-2026-80733

CVE-2026-80733 affects the Linux kernel 's sk_mc_loop() networking function. When called for non-INET sockets—such as AF_PACKET sockets sending packets over virtual devices like VRF or ipvlan —the function falls through its switch statement and triggers a spurious WARN_ON_ONCE(1) . Since non-INET...

CVE-2026-53706 PREVAIL: ALU32 pointer arithmetic accepted without is64 gate — verifier emits false PASS for pointer-corrupting programs

PREVAIL is a Polynomial-Runtime EBPF Verifier using an Abstract Interpretation Layer. Prior to version 0.2.4, the prevail eBPF verifier accepts ALU32 ADD and SUB instructions that operate on pointer-typed registers without checking the is64 flag. Because ALU32 arithmetic zero-extends the 32-bit...

kernel: fanotify: fix false positive on permission events

A flaw was found in the Linux kernel's fanotify subsystem. This vulnerability allows for a bypass of permission checks because the fsnotifygetmarksafe function may incorrectly return false for marks on unrelated groups. This could enable an attacker to perform unauthorized actions by circumventin...
