Vulnerability from fkie_nvd - Published: 2024-05-01 06:15 - Updated: 2025-11-03 22:16
Severity ?
Summary
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix slab-out-of-bounds in smb_strndup_from_utf16()
If ->NameOffset of smb2_create_req is smaller than Buffer offset of
smb2_create_req, slab-out-of-bounds read can happen from smb2_open.
This patch set the minimum value of the name offset to the buffer offset
to validate name length of smb2_create_req().
