CVE-2026-90206 nvmet: fix max_qid race between configfs and controller allocation

In the Linux kernel, the following vulnerability has been resolved: nvmet: fix maxqid race between configfs and controller allocation The function nvmetsubsysattrqidmaxstore can race against nvmetallocctrl when a subsystem's maxqid limit is modified. Suppose maxqid is currently 64. If...

CVE-2026-90206

CVE-2026-90206 is a race condition in the Linux kernel's nvmet (NVM Express Target) subsystem. The function nvmet_alloc_ctrl() allocates queue memory based on the subsystem's current max_qid , but a concurrent write via configfs can increase max_qid before the new controller is added to the subsy...

CVE-2026-90190 null_blk: use DEFINE_MUTEX for the file-scope mutex

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-2026-90190

CVE-2026-90190 affects the Linux kernel null_blk module. In null_init(), the call to mutex_init(&lock) occurs after configfs_register_subsystem(), which exposes the nullb subsystem to userspace. A racing mkdir() into /sys/kernel/config/nullb/ can reach null_find_dev_by_name() → mutex_lock(&lock) ...

CVE-2026-90185

This Linux kernel vulnerability affects the null_blk driver's configfs attribute store path. The NULLB_DEVICE_ATTR _store handlers fail to take the device lock, so concurrent stores on separate file descriptors race . For apply_fn attributes (submit_queues, poll_queues), a losing store can overwr...

EUVD-2026-81777

In the Linux kernel, the following vulnerability has been resolved: nullblk: serialize configfs attribute updates with device setup The attribute store methods generated with NULLBDEVICEATTR refuse to change the configuration of a live device by testing NULLBDEVFLCONFIGURED, but that flag is only...

CVE-2026-90184

CVE-2026-90184 is a race condition in the Linux kernel's null_blk block device driver. Configfs attribute store methods (e.g., for zoned) run concurrently with null_add_dev() without holding a lock, allowing device configuration to change mid-setup. This can lead to a failed device setup (-EIO vi...

CVE-2026-90168

CVE-2026-90168 affects the ksmbd SMB server component of the Linux kernel . The root cause is a lifetime mismatch: deferred CHANGE_NOTIFY work retains an async message ID after the original request work is released. Because a durable handle can outlive its connection, connection teardown can dest...
