smb: client: fix missing iov bounds check in parse_posix_sids()<\/p>\n
In parse_posix_sids(), sidsbuf_end is calculated using the server-supplied
\nout_len without being validated against the actual length of the received
\niov (iov_len).<\/p>\n
If a server provides an inflated out_len, sidsbuf_end will point past the
\nend of the iov. This defeats the bounds guards in posix_info_sid_size(),
\nallowing out-of-bounds reads into adjacent kernel memory.<\/p>\n
Fix this by rejecting responses where the calculated sidsbuf_end would
\nexceed the received iov boundaries or cause pointer wraparound.<\/p>\n","protected":false},"excerpt":{"rendered":"
