Last modified
CVE-2025-37808 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: crypto: null - Use spin lock instead of mutex As the null algorithm may be freed in softirq context through af_alg, use spin locks instead of mutexes to protect the default null algorithm.. EPSS estimates a 0.17% chance of exploitation in the next 30 days.
