CVE-2026-31526

Summary: CVE-2026-31526 concerns the Linux kernel BPF verifier. A defect in exception exits for BPF subprograms allowed ORC unwinding to proceed without releasing user-held locks, risking resource leaks and instability. The root cause: process_bpf_exit_full() could set check_lock=false for except...

kernel: smc: Use __sk_dst_get() and dst_dev_rcu() in smc_clc_prfx_match()

A flaw was found in the Linux kernel’s SMC Shared Memory Communication module: in smcclcprfxmatch, the function is called from smclistenwork without proper RCU or RTNL protection. The code previously used skdstgetsk-dev, which can lead to a use-after-free UAF condition if the sk’s destination is...
