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

Description The Linux kernel contains a null pointer dereference issue within the ntfs3 file system. Specifically, the vulnerability occurs in the ntfs lookup() function when handling MFT records that are not base records, potentially leading to a null pointer dereference in inode->i op. This can occur during a directory search, specifically within the dir search u() function, and subsequently in d splice alias() and d flags for inode().

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