Linux Kernel is a topic tracked in our intelligence system with 5 linked articles.
Two CVSS 9.0 remote code execution flaws in the Linux kernel's built-in KSMBD SMB server (ZDI-CAN-33774 and ZDI-CAN-33549) were disclosed publicly on mailing lists before any mainline kernel fix exists, with one exploitable pre-authentication.
CVE-2026-64531 (OVSwrap) in the Linux kernel Open vSwitch datapath enables local privilege escalation to root; public exploit covers ~800 kernel builds; CVSS 7.8.
A researcher claims AI helped turn a Linux traffic-control race into a root exploit, underscoring AI-assisted vulnerability development as a new risk for Linux-based systems.
Google paid $250k for reporting a Linux KVM guest-VM escape (CVE-2026-53359) with a proof-of-concept, while a second vulnerability GhostLock earned $92k; both have patches in the Linux kernel and pose cloud-virtualization isolation risks.
A high-severity Linux vulnerability caused by a single errant character could allow a use-after-free exploit to evade sandbox defenses.
Restartable sequences (rseq) on Linux promise dramatic lock-free, multi-core performance gains, but are Linux-only today and rely on hand-written assembly or advanced tooling; benchmarks claim 3x-43x speedups in malloc-like workloads across various CPUs, with significant portability and ecosystem implications ahead.
