[UPDATE] [medium] Linux Kernel: Multiple vulnerabilities
A local attacker can exploit multiple vulnerabilities in the Linux Kernel to bypass security measures, cause a denial of service, and potentially execute code.
CSIRTS triage
- What
- Multiple vulnerabilities in the Linux Kernel can lead to denial of service and other impacts.
- Who is affected
- Deployments of the Linux Kernel are affected.
- Urgency
- Remediation is important as the vulnerabilities could be exploited, although not confirmed.
- Action
- Apply the latest security updates for the Linux Kernel.

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-2026-532780.11% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 1% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-532790.12% 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-2026-532800.11% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 1% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-532810.13% 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-2026-532820.12% 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-2026-532830.12% 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-2026-532840.43% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 36% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-532850.11% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 1% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2026-532860.13% 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-2026-532870.12% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 2% of all EPSS-scored CVEs.
