CVE-2026-31423

The CVE-2026-31423 issue affects the Linux kernel’s net/sched sch_hfsc; rtsc_min() can divide by a value derived from the difference of large u64 slopes, risking a divide-by-zero when the difference equals 2^32. The fix widens the internal counter to u64 and replaces do_div() with div64_u64() to ...

CVE-2026-23379

A flaw was found in the Linux kernel's net/sched: ets module. A local user can exploit an integer overflow vulnerability when the system calculates weighted round-robin WRR weights for network traffic. This overflow can lead to a divide-by-zero error, causing the kernel to panic and resulting in ...

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...
