CVE-2024-35953
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.
Does this matter?
Lower severity and a low EPSS score (0.17%). Track it; it rarely justifies an emergency change on its own.
Description
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.
