CVE-2022-50841

The CVE covers a Linux kernel NTFS3 parsing flaw: when parsing MFT attributes, an overflow in the attribute size calculation could let Add2Ptr(attr, asize) exceed bounds, enabling an out-of-bounds memory R/W. The issue has been mitigated by adding an overflow check for attribute sizes in fs/ntfs3...
