"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nsparc: fix accurate exception reporting in copy_{from_to}_user for UltraSPARC\n\nThe referenced commit introduced exception handlers on user-space memory\nreferences in copy_from_user and copy_to_user. These handlers return from\nthe respective function and calculate the remaining bytes left to copy\nusing the current register contents. This commit fixes a couple of bad\ncalculations. This will fix the return value of copy_from_user and\ncopy_to_user in the faulting case. The behaviour of memcpy stays unchanged."
