CVE-2026-89737

CVE-2026-89737 affects the Linux kernel USB Type-C Thunderbolt altmode driver. The root cause is a use-after-free in tbt_altmode_remove(), which drops the plug and cable references without first draining tbt->work. The work function can dereference those freed references and can also requeue i...

CVE-2026-89738

CVE-2026-89738 is a use-after-free in the Linux kernel's at91_udc USB gadget driver. In polled-VBUS mode , a self-restarting timer/work cycle is not drained before the udc object is freed during a normal driver unbind or probe failure, allowing a pending or running timer callback to dereference f...

CVE-2026-89647

CVE-2026-89647 affects the Linux kernel's Ceph file system . The function ceph_cap_reclaim_work() enters a busy loop by re-queuing itself whenever ceph_trim_dentries() returns -EAGAIN, which occurs when a lease walk exhausts its scan budget with no cap pressure and all leases still valid. The dir...

CVE-2026-89603

CVE-2026-89603 is a race condition in the Linux kernel's syscall_trace_enter() that allows seccomp filter bypass via ptrace. When a thread is stopped for ptrace, another thread can install a seccomp filter with SECCOMP_FILTER_FLAG_TSYNC; however, syscall_trace_enter() evaluates a cached 'work' va...
