fkie_cve-2026-31480

In the Linux kernel, the following vulnerability has been resolved:

tracing: Fix potential deadlock in cpu hotplug with osnoise

The following sequence may leads deadlock in cpu hotplug:

task1 task2 task3 ----- ----- -----

mutex_lock(&interface_lock)

[CPU GOING OFFLINE]

cpus_write_lock(); osnoise_cpu_die(); kthread_stop(task3); wait_for_completion();

osnoise_sleep(); mutex_lock(&interface_lock);

cpus_read_lock();

[DEAD LOCK]

Fix by swap the order of cpus_read_lock() and mutex_lock(&interface_lock).

WID-SEC-W-2026-1252 — Linux Kernel: Mehrere Schwachstellen

Ein Angreifer kann mehrere Schwachstellen im Linux Kernel ausnutzen, um einen Denial of Service Angriff durchzuführen, Sicherheitsmaßnahmen zu umgehen, Informationen offenzulegen, andere nicht näher spezifizierte Auswirkungen zu verursachen und möglicherweise Code auszuführen.
