CVE-2026-53273

The CVE-2026-53273 entry applies to the Linux kernel tee/optee path and fixes a use-after-free in the supplicant interaction. The root cause was a race where, if the client exits before the supplicant finishes, a freed request could be dereferenced via supp->idr. The patch serializes access to...

CVE-2026-53262

Affected component: Linux kernel l2tp PPPoL2TP ioctl path. The vulnerability arises because pppol2tp_ioctl() read sock->sk->sk_user_data without locks or reference counting. A controllable sleep during copy_from_user (e.g., userfaultfd sleep) could allow a concurrent socket close to trigger...

CVE-2026-53204

The CVE-2026-53204 issue concerns the Linux kernel firmware component for Stratix10 RSU. A NULL pointer dereference could occur if rsu_send_msg() times out during probe and subsequent error cleanup would still queue messages on a cleared channel. The fix adds proper cleanup: remove the async clie...

CVE-2026-53175

The CVE-2026-53175 entry documents a Linux kernel use-after-free in fragment reassembly during netns teardown. Specifically, fqdir_pre_exit() flushes fragment queues but may leave freed skbs referenced via fragments_tail and last_run_head, enabling a later dereference when a stalled fragment resu...
