CVE-2022-50056

Status: AnalyzedMedium (5.5)—

In the Linux kernel, the following vulnerability has been resolved:

fs/ntfs3: Fix missing i_op in ntfs_read_mft

There is null pointer dereference because i_op == NULL. The bug happens because we don't initialize i_op for records in $Extend.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
