CVE-2026-74660

In the Linux kernel, the following vulnerability has been resolved: netfilter: ebtnflog: pin the NFLOG backend nflogunregister runs after the per-net teardown so its final RCU grace period also drains readers that obtained the logger from a per-net binding. However, ebtnflog passes an explicit UL...

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 ...

grub2: Missing unregister call for gettext command may lead to use-after-free

A Use-After-Free vulnerability has been discovered in GRUB's gettext module. This flaw stems from a programming error where the gettext command remains registered in memory after its module is unloaded. An attacker can exploit this condition by invoking the orphaned command, causing the applicati...
