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

Description An out-of-bounds write exists in the ocfs2 write end inline() function. The issue occurs because ocfs2 try to write inline data() relies on the on-disk id count field to determine if a write fits within inline data. On a corrupted filesystem, the id count can exceed the physical maximum inline data capacity, leading to a write that overflows the inode block buffer into an adjacent freed page.

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