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

ksmbd: fix out-of-bounds in parse_sec_desc()

If osidoffset, gsidoffset and dacloffset could be greater than smb_ntsd struct size. If it is smaller, It could cause slab-out-of-bounds. And when validating sid, It need to check it included subauth array size.
