CVE-2026-74267

The CVE concerns the Linux kernel’s traffic scheduler (net/sched sch_codel). During a peek when codel drops packets, qdisc_tree_reduce_backlog is called before the qlen is re-incremented, potentially deactivating the parent class while 1 packet remains, risking a wild memory access in certain qdi...

CVE-2026-74265

The CVE describes a Linux kernel fix in net: mana where gdma queue id is now initialized to INVALID_QUEUE_ID immediately after allocation. Previously, mana_gd_create_mana_wq_cq() left queue->id as 0 until mana_create_wq_obj() set the firmware-returned id; if creation failed before that, cleanu...

CVE-2026-74264

CVE-2026-74264 affects the Linux kernel watchdog code. The root issue is a race in refcount tracking between netdev_watchdog_up() and dev_watchdog(), caused by using dev->watchdog_dev_tracker without proper synchronization, which could lead to a use-after-free and list corruption (list_del cor...
