CVE-2026-74675

In the Linux kernel, the following vulnerability has been resolved: vt: stabilize tty reference in kbdkeycode with ttyportttyget kbdkeycode reads vc-port.tty without acquiring a tty reference, racing against conshutdown which clears port.tty under a different lock. Use ttyportttyget/ttykrefput to...

CVE-2026-74692

In the Linux kernel, the following vulnerability has been resolved: net/smc: fix TOCTOU race between smclistenout and listener close smclistenout reads lsmc-sk.skstate without the listener lock, then acquires locksocknested only after the check passes. This opens a window where smccloseactive can...

In the Linux kernel, the following vulnerability has been resolved: net: smc: fix splice entry lifetime imbalance in smcrxsplice smcrxsplice passes pages to splicetopipe before taking the references that cover the lifetime of each splice entry. In the VM-backed RMB path, splicetopipe may drop...

EUVD-2026-64408

In the Linux kernel, the following vulnerability has been resolved: accel/amxdna: Fix page-insertion errors in amdxdnainsertpages Two error paths in amdxdnainsertpages called vma-vmops-closevma before returning an error code to the caller. This is incorrect: amdxdnagemobjmmap registers an HMM...

CVE-2026-74721

A vulnerability in the Linux kernel's accel/amxdna driver (AMD DNA accelerator) involves two error paths in amdxdna_insert_pages() that incorrectly call vma->vm_ops->close(vma) before the mmap syscall returns. This prematurely drops the shmem pages_pin_count and the GEM object reference bac...

EUVD-2026-64405

In the Linux kernel, the following vulnerability has been resolved: devlink: fix net namespace reference leak in reload devlinknlreloaddoit calls devlinknetnsget, which returns a net with a held reference. When the requested namespace differs from the current one and the reload action is not...

CVE-2026-74718

This vulnerability affects the Linux kernel devlink subsystem. In devlink_nl_reload_doit(), a call to devlink_netns_get() acquires a reference to a network namespace. When the requested namespace differs from the current one and the reload action is not DRIVER_REINIT, the function returns -EOPNOT...
