CVE-2026-98797

A flaw was found in the Linux kernel. A local user with network administration privileges in a network namespace can cause a Denial of Service (DoS) by triggering an out-of-bounds memory read. When redirecting packets between network interfaces with differing numbers of transmit queues, the kernel fails to properly cap queue mappings during egress traffic scheduling. This flaw allows an attacker to cause the kernel to read out-of-bounds memory, resulting in a system crash.
