CVE-2026-89655 ceph: fix UAF in __kick_flushing_caps() on cf entry freed during unlock

In the Linux kernel, the following vulnerability has been resolved: ceph: fix UAF in kickflushingcaps on cf entry freed during unlock listforeachentry iterates ci-icapflushlist but drops icephlock to send cap messages. During the unlock window, handlecapflushack can acquire icephlock, detach cf...

CVE-2026-89655

A use-after-free (UAF) vulnerability exists in the Linux kernel's Ceph file system component, specifically in the __kick_flushing_caps() function. The root cause is a race condition : the function iterates over ci->i_cap_flush_list using list_for_each_entry() but drops i_ceph_lock to send cap ...

CVE-2026-80932

A use-after-free vulnerability in the Linux kernel's vsock/virtio component is triggered during virtio_vsock_remove(). The function flushes work items before freeing the virtio_vsock object, but the flush order ignores dependencies: send_pkt_work can queue rx_work after the remove path has alread...
