CVE-2026-90109

A flaw was found in the Linux kernel. A local attacker with root privileges could exploit a 32-bit integer overflow vulnerability in the networking scheduler's gred, bfifo, and plug enqueue functions. This occurs when the queue backlog, stored as a 32-bit integer, exceeds 4 Gigabytes GiB. The...
