On i386, the smallest attempted size is 320 bytes, but the kernel's saved_auxv is only 56 * sizeof(unsigned long), or 224 bytes. prctl_set_mm_map() therefore rejects all three attempts, and setup reports TBROK. With no supported_archs restriction, the cve runtest entry runs this test on 32-bit x86. Verdict - Needs revision --- Note: The agent can sometimes produce false positives although often its findings are genuine.
