CVE-2026-24088: Missing Authentication for Critical Function in Boot

Affected Software

Remediation

Recommended actions to resolve this vulnerability, in priority order.

1. Configuration

   Enable authentication for critical boot functions so that any operation that modifies or writes the boot partition requires proper authentication/authorization to prevent unauthorized write access and loading of a customized bootloader.

   Boot / boot partition authentication for critical boot functions = enabled
2. Configuration

   Enforce cryptographic validation (digital signature verification) of the bootloader and contents of the boot partition before allowing them to be written or executed to mitigate the reported cryptographic issue.

   Boot / boot partition cryptographic verification of bootloader = enabled
3. Compensating control

   Restrict write access to the affected partition and firmware update interfaces to trusted administrators only, apply access controls/ACLs, and ensure physical security of devices to prevent unauthorized modifications while fixes are implemented.
