CVE-2026-90072 net/sched: sfq: clamp quantum to avoid signed overflow soft lockup

In the Linux kernel, the following vulnerability has been resolved: net/sched: sfq: clamp quantum to avoid signed overflow soft lockup sfqinit sets q-quantum = pschedmtuqdiscdevsch unsigned. A device with a huge MTU e.g. dummy with maxmtu == 0 accepting MTU 2147483634 makes pschedmtu return...

CVE-2026-90072

CVE-2026-90072 is a signed overflow vulnerability in the Linux kernel's net/sched: sfq (Stochastic Fairness Queuing) qdisc. In sfq_init(), the quantum value is set from psched_mtu(), which returns an unsigned value. A device with an extremely large MTU (e.g., a dummy device with max_mtu == 0 acce...

CVE-2026-54240 libde265: Pixel accessor signed integer overflow causes heap OOB read/write

libde265 is an open source implementation of the h.265 video codec. Versions prior to 1.1.1 use signed 32-bit arithmetic to calculate pixel offsets, allowing a crafted HEVC stream with large image dimensions to trigger an integer overflow and cause out-of-bounds heap reads or writes, potentially...
