CVE-2026-74695

A reference count leak in the Linux kernel's netfilter flowtable module occurs when skb_dst_set_noref() is called on a socket buffer that already holds a ref-counted dst_entry from earlier RX or routing steps. The overwrite of skb->_skb_refdst leaks the prior reference and triggers a DEBUG_NET...

CVE-2026-74675

A race condition in the Linux kernel's virtual terminal (vt) subsystem affects the kbd_keycode() function, which reads vc->port.tty without acquiring a proper tty reference. This races against con_shutdown(), which clears port.tty under a different lock, potentially leading to a use-after-free...

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-2026-74628

CVE-2026-74628 is a use-after-free in the Linux kernel's net/x25 (X.25 protocol) subsystem. The root cause is that x25 timers are armed with mod_timer() and cancelled with timer_delete(), meaning a pending timer holds no reference on the socket. Because x25_heartbeat_expiry() rearms unconditional...
