In the Linux kernel, the following vulnerability has been resolved: netfs: Fix potential deadlock in write-through mode Fix netfsadvancewritethrough to always unlock the supplied folio and to mark it dirty if it isn't yet written to the end. Unfortunately, it can't be marked for writeback until t...

EUVD-2026-45753

In the Linux kernel, the following vulnerability has been resolved: net/handshake: Use spinlockbh for hnlock nvmettcpstatechange, a socket callback that runs in BH context, can reach handshakereqcancel via nvmettcpschedulereleasequeue and tlshandshakecancel. handshakereqcancel acquires hn-hnlock...

CVE-2026-63980

CVE-2026-63980 affects the Linux kernel net/handshake path in NVMe targets. nvmet_tcp_state_change() can reach handshake_req_cancel() via nvmet_tcp_schedule_release_queue() and tls_handshake_cancel(), where hn_lock was acquired with spin_lock(). If a process-context thread holds the lock while a ...

CVE-2026-63977 dpll: zl3073x: use __dpll_device_change_ntf() and remove change_work

In the Linux kernel, the following vulnerability has been resolved: dpll: zl3073x: use dplldevicechangentf and remove changework The changework was introduced to send device change notifications from DPLL device callbacks without deadlocking on dplllock, since the callbacks are already invoked...

CVE-2026-63977

The CVE-2026-63977 entry concerns the Linux kernel dpll ( zl3073x ) subsystem. The fix replaces the change_work mechanism with the exported __dpll_device_change_ntf(), calling it directly while holding dpll_lock, and removes the change_work infrastructure. This addresses a race where change_work ...
