CVE-2026-89972

In the Linux kernel, the following vulnerability has been resolved: nvme: add missing SRCU grace period in error path nvmeallocns error path at outunlinkns removes ns from the namespace head siblings list with listdelrcu&ns-siblings but does not wait for SRCU readers before freeing the namespace...

CVE-2026-89972

CVE-2026-89972 is a use-after-free vulnerability in the Linux kernel NVMe subsystem . The error path in nvme_alloc_ns() removes a namespace from the siblings list via list_del_rcu() but fails to call synchronize_srcu() before freeing the namespace struct. Concurrent readers in nvme_find_path() an...
