https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D209661 Konstantin Belousov <kib@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |kib@FreeBSD.org --- Comment #3 from Konstantin Belousov <kib@FreeBSD.org> --- (In reply to CTurt from comment #2) Suppose that uap->start is > 0x80000000, and uap->length is large enough so that the sum appears under the 3 pages * 8. Then negative i falls under the loop condition and causes wrong accesses. WRT return of success in this case, right, thank you for noting, I will fix= it as well. --=20 You are receiving this mail because: You are on the CC list for the bug.=
