[NEW] [medium] Linux Kernel: Multiple vulnerabilities allow unspecified attack
An attacker can exploit multiple vulnerabilities in the Linux Kernel to perform an unspecified attack, potentially bypass security measures, cause denial-of-service conditions, or disclose confidential information.
CSIRTS triage
- What
- Multiple vulnerabilities in Linux Kernel allow unspecified attacks including security bypass, denial of service, and information disclosure.
- Who is affected
- All systems running affected Linux Kernel versions.
- Urgency
- Medium; multiple CVEs affecting kernel security but no active exploitation confirmed.
- Action
- Apply kernel security updates addressing CVE-2026-74580 through CVE-2026-74587.

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-2026-745800.17% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 6% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-745810.17% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 6% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-745820.16% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 5% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-745830.17% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 6% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-745840.17% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 6% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-745850.18% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 7% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-745860.18% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 7% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-745870.18% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 7% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-745880.18% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 7% of all EPSS-scored CVEs.
