CVE-2026-74687

This vulnerability affects the Linux kernel 's at91sam9_wdt watchdog driver. The root cause is a use-after-free : the at91_ping() callback rearms the watchdog timer, but timer_delete() neither waits for a running callback nor prevents rearm, so during probe failure or driver removal the timer can...

CVE-2026-74677

CVE-2026-74677 is a use-after-free in the Linux kernel's ipheth USB network driver. The root cause is that ipheth_sndbulk_callback() re-arms the carrier_work delayed work on any non-zero URB status without checking whether the interface is still up. After ipheth_close() drains the work, a late UR...
