An exploitable information disclosure vulnerability exists in the dev_read functionality of F2fs-Tools F2fs.Fsck 1.13. A specially crafted f2fs filesystem can cause an uninitialized read resulting in an information disclosure. An attacker can provide a malicious file to trigger this vulnerability.
The product incorrectly checks a return value from a function, which prevents it from detecting errors or exceptional conditions.
