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

Description The Linux kernel contains a use-after-free issue in the do rbd add() function when rbd dev create() fails. This occurs when ownership of structures like rbd dev->rbd client, rbd dev->spec, and rbd dev->opts is transferred prematurely, leading to their potential freeing during rbd dev create() before returning to do rbd add(). The issue was found by Linux Verification Center (linuxtesting.org) with SVACE, and an incomplete patch was submitted by Natalia Petrova.

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