Multiple vulnerabilities in SUSE Linux kernel (July 31, 2026)
Multiple vulnerabilities have been discovered in SUSE Linux kernel. Some of them allow an attacker to cause data confidentiality breach, data integrity breach and security policy bypass.
CSIRTS triage
- What
- Multiple kernel vulnerabilities enabling data confidentiality and integrity breaches and security policy bypass.
- Who is affected
- SUSE Linux Enterprise systems and openSUSE installations running vulnerable kernel versions.
- Urgency
- High; kernel vulnerabilities affecting confidentiality, integrity, and policy enforcement require immediate patching.
- Action
- Apply SUSE Linux kernel security updates via zypper patch to address all 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-2026-431980.30% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 22% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-433660.13% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 3% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-461190.53% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 42% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-432980.12% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 2% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-532720.12% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 2% of all EPSS-scored CVEs.
