Last modified: 2023-10-30 05:24:43 UTC
There an out-of-bounds read at fs/ntfs.c, a physically present attacker may leverage that by presenting a specially crafted NTFS file system image to read arbitrary memory locations. A successful attack may allow sensitive data cached in memory or EFI variables values to be leaked presenting a high Confidentiality risk.
