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...

CVE-2026-74629

In the Linux kernel, the following vulnerability has been resolved: net/dibs: Correct freeing of dmbclientidarr A dibs device interrupt handler can be active after dibsdevdel and may still access dmbclientidarr. UAF In case of a failure in dibsdevadd being called by dibslodevprobe dmbclientidarr ...

CVE-2026-74629

CVE-2026-74629 affects the Linux kernel's dibs (Device In-Band Signaling) subsystem and involves two memory-management defects in the lifecycle of dmb_clientid_arr. First, a use-after-free occurs when a dibs device interrupt handler remains active after dibs_dev_del() and continues to access the ...

CVE-2026-74627

CVE-2026-74627 affects the Linux kernel's net: devmem component. The root cause is improper mixing of net_iov and page-backed fragments within a single skb in the zerocopy_fill_skb_from_devmem() function, which causes a crash downstream in the stack. Red Hat classifies the impact as Denial of Ser...
