CVE-2026-80556

CVE-2026-80556 is a use-after-free bug in the Linux kernel's atmel-mci MMC driver. The root cause is a race condition in atmci_remove: when the module is removed, the host structure (allocated via devm_kzalloc) is freed after the remove callback returns, but &host->bh_work—which can be queued ...

CVE-2026-80553

CVE-2026-80553 affects the Linux kernel 's s390/vfio_ccw driver, used for channel-to-channel I/O on the s390 architecture. The root cause is that the io_work and crw_work workqueues are initialized during device setup but never cancelled during device release (_release_dev). This means work items...

CVE-2026-80553 s390/vfio_ccw: Cancel existing workqueues

In the Linux kernel, the following vulnerability has been resolved: s390/vfioccw: Cancel existing workqueues The initialization of the iowork and crwwork workqueues begs the question of whether they should be un-initialized. Add the corresponding cleanup tags in releasedev to ensure work isn't...

CVE-2026-80521

CVE-2026-80521 is a use-after-free in the Linux kernel's af_unix subsystem, specifically in the garbage collection (GC) logic for strongly connected components (SCC). A race in unix_del_edge() allows the GC to free a dead SCC partially when a concurrent send() of a socket and close() of other soc...

CVE-2026-80521 af_unix: Unlink scc_entry in unix_del_edge().

In the Linux kernel, the following vulnerability has been resolved: afunix: Unlink sccentry in unixdeledge. Kyle Zeng reported that GC could free a dead SCC partially. The scenario is as follows: 1 Create two SCCs: X -. A B ^--' 2 Run the following concurrently: 2-1 send sk-B to sk-B from sk-X 2-...

CVE-2026-80519 ovpn: finish crypto callback cleanup before peer release

In the Linux kernel, the following vulnerability has been resolved: ovpn: finish crypto callback cleanup before peer release Crypto completion callbacks hold both key-slot and peer references. The peer reference pins the netdev, and dropping the last peer reference can let netdev unregistration a...

CVE-2026-80519

CVE-2026-80519 affects the Linux kernel OpenVPN module (ovpn) due to an incorrect ordering of reference cleanup in crypto completion callbacks. Specifically, the peer reference (which pins the netdev) is dropped before the callback finishes its own cleanup, allowing ovpn_crypto_key_slot_put to sc...

CVE-2026-74753

This use-after-free vulnerability in the Linux kernel's perf subsystem occurs because perf_event_open() accepts events in the EXIT state as group leaders, rejecting only REVOKED and DEAD events. After perf_event_remove_on_exec() detaches group relationships, a new sibling can be linked to the det...
