Re: Retrospective by 'gpg.fail' authors

Unreported 0-day RCE in gpgsm 2.4.9 disclosed via gpg.fail talk, triggered by importing a malicious certificate with --debug options.

A retrospective by the gpg.fail authors revealed a remote code execution vulnerability in gpgsm 2.4.9, triggered when invoked as "gpgsm --debug all --import" with a malicious certificate file. The researchers did not report the issue to GnuPG, leaving it unpatched as an apparent 0-day. Exposure appears limited since it requires importing untrusted certificates with debug options enabled.

CVE-2026-89775: Guest-to-Host Escape in KVM/arm64

Disclosed CVE-2026-89775 lets a guest VM escape to the host on KVM/arm64 systems with nested virtualization enabled.

Researcher Hyunwoo Kim disclosed CVE-2026-89775, a guest-to-host escape in KVM/arm64, after the embargo agreed with linux-distros maintainers expired. The root cause is a type truncation of the stage-1 walk level that makes a size computation return 0, the value meaning 'size unknown'. The VNCR pseudo-TLB invalidation path then interprets that 0 as a valid value on ARM64 hosts where nested virtualization is enabled.
