In the Linux kernel, the following vulnerability has been resolved: drbd: Balance RCU calls in drbd_adm_dump_devices() Make drbd_adm_dump_devices() call rcu_read_lock() before rcu_read_unlock() is called. This has been detected by the Clang thread-safety analyzer.

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.
