      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nsmb: client: fix missing iov bounds check in parse_posix_sids()\n\nIn 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).\n\nIf 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.\n\nFix this by rejecting responses where the calculated sidsbuf_end would\nexceed the received iov boundaries or cause pointer wraparound.",
