We have found a bug in jvm with our exceptions reporting system in Idea.
It affects jdk11 and jdk17 ( can't say anything about jdk19)
We knows it's a regression, jdk11.0.13 is not affected, jdk11.0.14+ is affected.
Can't say when it appeared in jdk17
In stubGenerator_x86_32.cpp, in
void xmm_copy_forward(Register from, Register to_from, Register qword_count) {
...
} else if (UseAVX == 2) {
        __ vmovdqu(xmm0, Address(from, 0));
        __ vmovdqu(Address(from, to_from, Address::times_1, 0), xmm0);
        __ vmovdqu(xmm1, Address(from, 32)); <--- THIS LINE
        __ vmovdqu(Address(from, to_from, Address::times_1, 32), xmm1);

The issue happens when it copies near the bound of mapped memory region
the highlighted line copies 32 bytes, copying first 16 of them would be ok, but secodn 16 bytes would be located in a memory region not mapped in the current process, resuling in a crash.
Few snippets from crash reports:
