High (7.1) in linux linux kernel. EPSS 0.5% chance of exploitation in the next 30 days.
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.
