In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
smb: client: fix reparse buffer bounds in cifs_query_reparse_point()<\/p>\n
In cifs_query_reparse_point(), the start >= end check before casting to
\nstruct reparse_data_buffer * only ensures the start pointer is within the
\nresponse. It fails to verify that there is enough space remaining for the
\nfixed 8-byte header of the structure.<\/p>\n
If a server provides a DataOffset that leaves less than 8 bytes remaining,
\nthe check passes, but subsequent reads of ReparseTag and ReparseDataLength
\nwill occur out-of-bounds.<\/p>\n
Fix this by ensuring the remaining space is at least the size of the
\nreparse_data_buffer structure before accessing its fields.<\/p>\n","protected":false},"excerpt":{"rendered":"
