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.
