In the Linux kernel, the following vulnerability has been resolved: nullblk: use DEFINEMUTEX for the file-scope mutex In nullinit, mutexinit&lock currently happens after configfsregistersubsystem, which exposes the nullb subsystem to userspace. A racing mkdir into /sys/kernel/config/nullb/ can...

CVE-2026-90187: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: nullblk: free zones array on device power-off nullinitzoneddev allocates dev-zones when a zoned device is powered on, but nulldeldev never frees it on power-off; dev-zones is only freed later in nullfreedev, when the configfs...

CVE-2026-90186: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: nullblk: reject per-device queue resize for shared tag set When sharedtags is enabled, nullsetuptagset makes the device use the global tagset, whose driverdata stays NULL. nullmapqueues therefore falls back to the module-wide...
