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 flaw was found in the Linux kernel's Segment Routing over IPv6 (seg6) component. This vulnerability allows a local user to trigger the reading of uninitialized memory due to incorrect validation of nexthop address lengths. Successful exploitation could lead to information disclosure or a denial of service.
