CVE-2026-63982

A flaw was found in the Linux kernel's network scheduler component. This vulnerability occurs when the mirred action, used for redirecting network traffic, fails to properly detect a redirection loop. An attacker can exploit this by crafting specific network configurations that cause packets to b...
