highCVE-2026-68429 CVE-2026-68430 CVE-2026-68431 CVE-2026-68432 CVE-2026-68433 CVE-2026-68434

A remote, anonymous attacker can exploit multiple vulnerabilities in Linux Kernel to conduct an unspecified attack, including potentially arbitrary code execution, disclosure of information, manipulation of data, or denial-of-service conditions.

CSIRTS triage

vendor: Linux product: Linux Kernel Remote code execution Information disclosureOtherDenial of service

What: Multiple vulnerabilities in the Linux Kernel enable unspecified attacks including code execution, information disclosure, data manipulation, and denial of service.
Who is affected: Linux systems running vulnerable kernel versions.
Urgency: High; remote unauthenticated attack vector with multiple severe impact classes.
Action: Update the Linux Kernel to a patched version addressing the identified CVEs.

Exploitation outlook

EPSS (FIRST.org) estimates each CVE’s probability of exploitation in the next 30 days — here is the CSIRTS.com read on those numbers.

Low exploitation riskCVE-2026-684290.17% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 7% of all EPSS-scored CVEs.
