[UPDATE] [high] Linux Kernel: Multiple Vulnerabilities
An attacker can exploit multiple vulnerabilities in Linux Kernel to perform unspecified attacks that may possibly lead to a denial-of-service condition or cause memory corruption.
CSIRTS triage
- What
- Multiple vulnerabilities in the Linux Kernel may lead to denial of service or memory corruption.
- Who is affected
- Systems running affected versions of the Linux Kernel are vulnerable.
- Urgency
- High priority; denial of service and memory corruption are possible and kernel updates should be deployed promptly.
- Action
- Update to a patched Linux Kernel version addressing CVE-2025-40178 through CVE-2025-40185.

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-2025-401780.21% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 11% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2025-401790.20% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 10% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2025-401800.19% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 9% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2025-401810.19% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 9% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2025-401820.14% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 4% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2025-401830.57% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 44% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2025-401840.18% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 8% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2025-401850.19% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 9% of all EPSS-scored CVEs.
- Low exploitation riskCVE-2025-401860.53% 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-2025-401870.59% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 45% of all EPSS-scored CVEs.
