"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ntracing/syscalls: Use copy_from_user for the faultable syscall buffer\n\nsyscall_copy_user_array() copies the buffer argument of faultable\nsyscalls (write, pwrite64, ...) with __copy_from_user(), which skips\naccess_ok(). Use copy_from_user() instead so a non-user address is\nrejected and the entry is recorded as faulted.\n\nIt could be a security concern for machines that trust perf a bit too\nmuch."
