CISA Flags Actively Exploited Linux Kernel CVE 'Copy Fail'
CISA has flagged a Linux kernel vulnerability dubbed 'Copy Fail' that enables root-level takeover across major distributions. The flaw is actively exploited and unpatched systems remain at risk; patches are available but adoption is not universal.
Infrastructure teams managing on-prem or hybrid Linux deployments should prioritize kernel patching and verify distribution update status. This complements ongoing supply-chain and container-image hardening for zero-trust architectures.
