**Name of the Vulnerable Software and Affected Versions:** Linux kernel (affected versions not specified) **Description:** A flaw exists in the Linux kernel related to `rcu read unlock()`. Specifically, a potential deadlock can occur during `rcu read unlock special()` when invoked within the `irq exit()` path, triggered by an Inter-Processor Interrupt (IPI). This issue arises from incorrect management of the irq work state. The vulnerability was identified when invoking a BPF program on the `trace tick stop()` tracepoint. **Recommendations:** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
