CVE-2026-45957
Description
A flaw was found in the Linux kernel's Read-Copy Update (RCU) mechanism. A missing recursion protection in the rcu_read_unlock() function can lead to an infinite loop, known as a deadloop, when a soft interrupt (softirq) is triggered. This issue can cause the system to become unresponsive, resulting in a Denial of Service (DoS).

Availability
Technical Impact: DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory); DoS: Amplification
