Last modified Jun 17, 2026

CVE-2022-25368 is a medium-severity vulnerability rated 4.7/10 on the CVSS scale. Spectre BHB is a variant of Spectre-v2 in which malicious code uses the shared branch history (stored in the CPU BHB) to influence mispredicted branches in the victim's hardware context. Speculation caused by these mispredicted branches can then potentially be used to cause cache allocation, which can then be used to infer information that should be protected.. EPSS estimates a 0.29% chance of exploitation in the next 30 days.
