CVE-2026-74617
A flaw was found in the Linux kernel's dibs device driver. The dibs-lock was not properly initialized when a dibs device was allocated, allowing a Global ID GID event interrupt to occur before the lock was ready. This could lead to the system attempting to acquire an uninitialized lock, potential...
CVE-2026-74617
In the Linux kernel, the following vulnerability has been resolved: dibs: initialise dibs-lock in dibsdevalloc dibs-lock is initialised by dibsdevadd, but a dibs device can already take interrupts before that call: ismprobe runs ismdevinit, and hence requestirq, before it calls dibsdevadd. No...

CVE-2026-74513
In the Linux kernel, the following vulnerability has been resolved: dibs: fix use-after-free of dmbnode in loopback attach/detach/unregister dibsloattachdmb, dibslodetachdmb and dibslounregisterdmb look up the dmbnode under dmbhtlock, drop the lock and only then operate on the node's refcount...
CVE-2026-74513
CVE-2026-74513 affects the Linux kernel where a use-after-free can occur in dibs loopback handling due to a race between hash-table lookup and refcount teardown of dmb_node. The fix makes hash table membership and refcount transitions atomic: final refcount_dec_and_test() and hash_del() are perfo...
