Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A resource leak exists in the error handling path of the mpc52xx lpbfifo probe() function on the powerpc/52xx architecture. Specifically, a call to request irq() is not balanced with a corresponding free irq(), leading to a resource leak when an error occurs. The issue is resolved by adding the missing free irq() call, mirroring the behavior in the remove function.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
