CVSS v3.1

Medium
| Vector | AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions:
Linux kernel (affected versions not specified)
Description:
A race condition in the Linux kernel's irqchip/gic-v4 component allows userspace to force a change of affinity for a VPE while it has already been unmapped, but the corresponding doorbell interrupt is still visible in /proc/irq/. The issue is resolved by checking the value of
vmapp count, which tracks whether the VPE is mapped or not, and returning an error in this case. This fix involves making vmapp count common to both GICv4.1 and its v4.0 ancestor.Recommendations:
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
