Just tried it. No, it did not crash the kernel on 5.15-rc1.
Following log was printed repeatedly:
[ 647.478557][ T6807] loop0: p1 p2 < > p3 p4
[ 647.478922][ T6807] loop0: p1 size 11290111 extends beyond EOD, truncated
[ 647.481111][ T6807] loop0: p3 size 1914664839 extends beyond EOD, truncated
[ 647.482512][ T6807] loop0: p4 size 3389030400 extends beyond EOD, truncated
It seems that this crash was fixed. Sorry for the dup report.
