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

Description The Linux kernel contains a flaw within the jbd2 fc wait bufs function that may lead to a use-after-free condition. This occurs because the function uses a buffer head (bh) after its reference count has been decremented, potentially resulting in access to freed memory. The issue is triggered when the buffer is used after the reference count is reduced.

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