CVE-2026-23379

CVE-2026-23379 affects the Linux kernel net/sched ETS offload path. The root cause was an overflow in WRR weight computation (q_sum, q_psum) due to using 32-bit unsigned integers, which could lead to division by zero. The documented fix is to switch q_sum and q_psum to 64-bit integers, preventing...
