Ubuntu.comUB:CVE-2024-26980CVE-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().
