0 CVE-2026-8863 is a vulnerability in OracleLinux(7.2) shim version 0.9 involving improper verification of cryptographic signatures. This flaw allows an attacker with administrative privileges or the ability to modify the boot process to bypass Secure Boot protections by exploiting Microsoft-signed UEFI SHIM bootloaders. Successful exploitation could enable arbitrary code execution before the operating system loads. No official patch or remediation guidance is currently provided, but a specific UEFI DBX update is required to block the vulnerable boot loaders.
