CVE-2025-38310 Details
Description
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.
A vulnerability in the Linux kernel's segment routing (seg6) implementation has been addressed. The issue arose because the kernel did not properly validate the length of nexthop addresses, allowing user space to specify a shorter length than required. This discrepancy could lead to the kernel accessing uninitialized memory. The vulnerability has been fixed by ensuring that the provided length matches the specified length exactly.
