The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - tracing: Add recursion protection in kernel stack trace recording A bug was reported about an infinite     recursion caused by tracing the rcu events with the kernel stack trace trigger enabled. The stack trace     code called back into RCU which then called the stack trace again. Expand the ftrace recursion protection     to add a set of bits to protect events from recursion. Each bit represents the context that the event is     in (normal, softirq, interrupt and NMI). Have the stack trace code use the interrupt context to protect     against recursion. Note, the bug showed an issue in both the RCU code as well as the tracing stacktrace     code. This only handles the tracing stack trace side of the bug. The RCU fix will be handled separately.
    (CVE-2026-23138)
