CVE-2026-43085

A flaw was found in the Linux kernel's netfilter component. When processing batched network filter (NFLOG) messages, the system fails to properly initialize a data structure, leading to the leakage of four bytes of uninitialized kernel memory. This vulnerability could allow a local attacker to gain access to sensitive information from the kernel's memory.

Red Hat acknowledges the upstream Linux kernel correction for «netfilter» as described in COMMENT_ZERO. Fixes are delivered through standard kernel errata for supported products. Operational exposure depends on whether this subsystem or driver is active in your configuration.
