Vulnerability from github – Published: 2024-05-20 12:30 – Updated: 2025-01-10 18:31

Details

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

accel/ivpu: Fix deadlock in context_xa

ivpu_device->context_xa is locked both in kernel thread and IRQ context. It requires XA_FLAGS_LOCK_IRQ flag to be passed during initialization otherwise the lock could be acquired from a thread and interrupted by an IRQ that locks it for the second time causing the deadlock.

This deadlock was reported by lockdep and observed in internal tests.

Severity ?

5.5 (Medium)
