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

Description The issue is related to the nilfs2 file system in the Linux kernel. Specifically, the helper function nilfs recovery copy block() of nilfs recovery dsync blocks() incorrectly calculates the on-page offset when copying repair data to the file's page cache. This flaw can cause data corruption and leak uninitialized memory bytes during the recovery process, particularly in environments where the block size is smaller than the page size.

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