Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description A vulnerability in the Linux kernel has been identified, specifically in the rcar-ep PCI module. The rcar pcie parse outbound ranges() function uses the devm request mem region() macro to request a needed resource, but a string variable on the stack is used to store a dynamically computed resource name, leading to undefined behavior. This can cause varying manifestations of errors, including garbage output or system crashes in rare cases. The issue is resolved by replacing the variable with the name of the previously requested resource.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
