commit 2d380889 upstream. Make sure to check for short transfers to avoid underflow in a loop condition when parsing the receive buffer. Also fix an off-by-one error in the incomplete sanity check which could lead to invalid data being parsed. Fixes: 8c209e67 ("USB: make actual_length in struct urb field u32") Fixes: 1da177e4 ("Linux-2.6.12-rc2") Reviewed-by:
