Detailsinfo

A vulnerability classified as critical has been found in Phoenix SecureCore for Intel Kaby Lake, SecureCore for Intel Coffee Lake, SecureCore for Intel Ice Lake, SecureCore for Intel Comet Lake, SecureCore for Intel Tiger Lake, SecureCore for Intel Jasper Lake, SecureCore for Intel Alder Lake, SecureCore for Intel Raptor Lake and SecureCore for Intel Meteor Lake. Affected is an unknown function of the component UEFI Variable Handler. The manipulation with an unknown input leads to a buffer overflow vulnerability. CWE is classifying the issue as CWE-120. The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:
