| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A use-after-free issue has been identified in the Linux kernel, specifically in the irqchip/gic-v2m component. The
gicv2m get fwnode() function is registered with the PCI subsystem as pci msi get fwnode cb(), but it is incorrectly marked as init, causing it to be freed while still being used. This can lead to a kernel paging request error, which can be reproduced on a Juno board with ACPI boot.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
