Positive Technologies (AI Summary)

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

Description A flaw exists in the Linux kernel’s nilfs2 filesystem implementation where a corrupted superblock data field, specifically s log block size, if excessively large, can lead to a shift-out-of-bounds error during the init nilfs() and load nilfs() functions. This can result in a kernel panic if panic on warn is enabled. The issue stems from an insufficient sanity check when determining the block size. The fix introduces a helper function to obtain the block size with added validation.

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