CVE-2025-38310
Last modified
CVE-2025-38310 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: seg6: Fix validation of nexthop addresses The kernel currently validates that the length of the provided nexthop address does not exceed the specified length. This can lead to the kernel reading uninitialized memory if user space provided a shorter length than the specified one. Fix by validating that the provided length exactly matches the specified one.. EPSS estimates a 0.14% chance of exploitation in the next 30 days.
