"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nlib/test_hmm: fail dmirror_fault() when the mirrored mm is gone\n\ndmirror_fault() is called from the dmirror_read() and dmirror_write()\nretry loops after dmirror_do_read() or dmirror_do_write() finds a missing\ndevice page table entry.\n\nIf the mirrored mm has already exited, mmget_not_zero() fails. The\ncurrent code returns 0 in that case, which tells the caller that faulting\nsucceeded even though no page was faulted and no device page table entry\nwas installed. The caller then retries the same address, hits -ENOENT\nagain, and can loop forever without making progress.\n\nReturn -EFAULT instead, so the ioctl fails when the mirrored mm is no\nlonger faultable."
