CVE-2023-5368
Last modified
CVE-2023-5368 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. On an msdosfs filesystem, the 'truncate' or 'ftruncate' system calls under certain circumstances populate the additional space in the file with unallocated data from the underlying disk device, rather than zero bytes. This may permit a user with write access to files on a msdosfs filesystem to read unintended data (e.g. from a previously deleted file). . EPSS estimates a 0.53% chance of exploitation in the next 30 days.
