CVE-2026-53128

A flaw was found in the Linux kernel's drbd component. Specifically, an imbalance in RCU (Read-Copy Update) calls within the drbd_adm_dump_devices() function could occur, where rcu_read_lock() was not properly invoked before rcu_read_unlock(). This concurrency issue, identified by a thread-safety analyzer, may lead to system instability or a denial of service.
