CVE-2026-53219

A flaw was found in the Linux kernel's netfilter xtables component. This vulnerability allows for information disclosure due to improper handling of percpu counter pointers during the copying of rule entry headers to userspace. A local attacker could exploit this by causing a fault in a userspace...
