Last modified

CVE-2020-15294 is a high-severity vulnerability rated 7/10 on the CVSS scale. Compiler Optimization Removal or Modification of Security-critical Code vulnerability in IntPeParseUnwindData() results in multiple dereferences to the same pointer. If the pointer is located in memory-mapped from the guest space, this may cause a race-condition where the generated code would dereference the same address twice, thus obtaining different values, which may lead to arbitrary code execution. EPSS estimates a 0.29% chance of exploitation in the next 30 days.
