Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A memory leak issue was resolved in the Linux kernel related to the UBI file system. The issue occurs when the
insert old idx() function fails during a specific process involving znode copying. Specifically, the copy znode() function allocates resources, and if insert old idx() subsequently fails, the allocated resources are not properly released, leading to a memory leak. The copy znode() function is split into resource allocation and znode replacement, and insert old idx() is similarly structured to facilitate resource cleanup in error handling paths. The processes add idx dirt() and layout leb in gaps() do not depend on each other.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
