Six stable Linux kernel releases patch CVE-2026-68480, a speculative execution vulnerability that could enable data leakage.
Speculative execution flaws can expose sensitive data across isolation boundaries, which is especially concerning for multi-tenant and containerized environments. The fix spans six kernel branches from 5.10 through 7.1, meaning a large installed base is potentially affected.
