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

Description A use-after-free issue exists in the Linux kernel, specifically in the ubi create volume() function. The problem arises when volume creation fails, and there is an attempt to access the eba tbl after it has been freed. This occurs due to redundant releasing of eba tbl. The issue is related to the ubi eba replace table() and ubi eba destroy table() functions, and the tbl->entries are freed after the eba tbl has been destroyed, leading to a use-after-free condition.

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