Vulnerability Details : CVE-2024-26980
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix slab-out-of-bounds in smb2_allocate_rsp_buf
If ->ProtocolId is SMB2_TRANSFORM_PROTO_NUM, smb2 request size
validation could be skipped. if request size is smaller than
sizeof(struct smb2_query_info_req), slab-out-of-bounds read can happen in
smb2_allocate_rsp_buf(). This patch allocate response buffer after
decrypting transform request. smb3_decrypt_req() will validate transform
request size and avoid slab-out-of-bound in smb2_allocate_rsp_buf().
