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

Description A memory leak issue has been identified in the Linux kernel, specifically in the renesas-rpc-if module. The problem occurs when the registration of the flash platform device fails during the probe, resulting in a platform-device leak. This issue is related to the error path in the memory management of the Linux kernel.

Recommendations To resolve this issue, update the Linux kernel to a version that includes the fix for the memory leak in the renesas-rpc-if module. Ensure that the updated kernel version properly frees the flash platform device in case of registration failure during probe.
