CVE-2026-74660

CVE-2026-74660 is a use-after-free in the Linux kernel's netfilter: ebt_nflog component. The ebt_nflog module passes an explicit ULOG log type to nf_log_packet() without holding a reference on the nfnetlink_log module, unlike the xt_NFLOG and nft_log frontends. This allows an ebtables nflog rule ...

In the Linux kernel, the following vulnerability has been resolved: futex: Prevent robust futex exit race some more A robust futex unlock stores 0 over the whole futex value - wiping FUTEXWAITERS - and wakes a single waiter. That wakeup is a one-shot notification: the protocol relies on its...

CVE-2026-74658

CVE-2026-74658 is a race condition in the Linux kernel robust futex exit handling. When a woken waiter is killed before it can acquire the futex or re-arm FUTEX_WAITERS , and a third task re-acquires the futex via the uncontended fast path, the notification is lost. The new owner sees no FUTEX_WA...
