This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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

KVM: arm64: vgic-its: Avoid potential UAF in LPI translation cache

There is a potential UAF scenario in the case of an LPI translation

cache hit racing with an operation that invalidates the cache, such

as a DISCARD ITS command. The root of the problem is that

vgic_its_check_cache() does not elevate the refcount on the vgic_irq

before dropping the lock that serializes refcount changes.

Have vgic_its_check_cache() raise the refcount on the returned vgic_irq

and add the corresponding decrement after queueing the interrupt.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
