CVE-2026-74628

This is a use-after-free vulnerability in the Linux kernel's net/x25 subsystem. The X.25 timers are armed with mod_timer() and cancelled with timer_delete(), which means a pending timer holds no reference to the socket. Because x25_heartbeat_expiry() rearms the timer unconditionally, it can reins...

EUVD-2026-64565

In the Linux kernel, the following vulnerability has been resolved: net/x25: fix use-after-free of the socket by its timers The x25 timers are armed with modtimer and cancelled with timerdelete, so a pending timer holds no reference on the socket and a cancel does not wait for a callback already...

CVE-2026-74629

CVE-2026-74629 affects the Linux kernel in the net/dibs subsystem. Two memory management flaws exist: a use-after-free occurs because a dibs device interrupt handler can remain active after dibs_dev_del() and still access dmb_clientid_arr, and a double free occurs when dibs_dev_add() fails during...

CVE-2026-74623

CVE-2026-74623 affects the Aquantia Atlantic network driver in the Linux kernel. The root cause is that aq_vec_deinit() drains TX rings with a single aq_ring_tx_clean() call limited to 256 descriptors and stops at hw_head, which no longer advances after hardware and NAPI are stopped. Completed de...

CVE-2026-74620

This Linux kernel vulnerability affects the net/sched subsystem, specifically the act_gact and act_police traffic control actions. The fallback control actions (TCA_GACT_PROB.paction and TCA_POLICE_RESULT) bypass the range check in tcf_action_check_ctrlact(), allowing user space to store TC_ACT_C...
