Aug 15 ENRICHED — CVE-2022-50262 (Linux). Received CVSS 5.5 and CPE data from NVD.
Description
In the Linux kernel, the following vulnerability has been resolved:
fs/ntfs3: Validate BOOT record_size
When the NTFS BOOT record_size field < 0, it represents a
shift value. However, there is no sanity check on the shift result
and the sbi->record_bits calculation through blksize_bits() assumes
the size always > 256, which could lead to NPD while mounting a
malformed NTFS image.
