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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N","score":4.7},"cwes":[],"references":["https://amperecomputing.com/products/security-bulletins/impact-of-spectre-bhb-on-ampere.html","https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-23960","https://developer.arm.com/support/arm-security-updates/speculative-processor-vulnerability/spectre-bhb","https://amperecomputing.com/products/security-bulletins/impact-of-spectre-bhb-on-ampere.html","https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-23960"],"products":["amperecomputing:ampere_altra_firmware","amperecomputing:ampere_altra_max_firmware","arm:cortex-a15_firmware","arm:cortex-a57_firmware","arm:cortex-a65_firmware","arm:cortex-a65ae_firmware","arm:cortex-a710_firmware","arm:cortex-a72_firmware","arm:cortex-a73_firmware","arm:cortex-a75_firmware","arm:cortex-a76_firmware","arm:cortex-a76ae_firmware","arm:cortex-a77_firmware","arm:cortex-a78_firmware","arm:cortex-a78ae_firmware","arm:cortex-a78c_firmware","arm:cortex-x1_firmware","arm:cortex-x2_firmware","arm:neoverse-e1_firmware","arm:neoverse-v1_firmware","arm:neoverse_n1_firmware","arm:neoverse_n2_firmware"],"source":"nvd","synced_at":"2026-10-19T21:29:06.454770966+00:00"},"epss":{"cve":"CVE-2022-25368","score":0.00299,"percentile":0.22624,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
