- Exploitation: No exploitation in the wild and no public exploit is recorded for the CVEs named.

CERT-FR has published a security advisory covering multiple vulnerabilities in the Linux kernel shipped with Debian trixie. The affected versions are those prior to 6.12.107-1. These vulnerabilities permit attackers to achieve privilege escalation, compromise data confidentiality, and cause denial of service. The advisory references twelve distinct CVEs spanning CVE-2025-40074 through CVE-2026-80725. Debian has published a security bulletin with patched kernel versions available for download and installation. Defenders running Debian trixie should prioritize updating to the patched kernel version to mitigate the risk of local privilege escalation and system compromise.
