CVSS 3.1
7.5 highCVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:HCVE-2024-31142
High (7.5). EPSS 17% chance of exploitation in the next 30 days.
Because of a logical error in XSA-407 (Branch Type Confusion), the
mitigation is not applied properly when it is intended to be used.
XSA-434 (Speculative Return Stack Overflow) uses the same
infrastructure, so is equally impacted.
