Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A slab-out-of-bounds issue has been resolved in the Linux kernel. The issue was observed while running self-tests on a KASAN enabled kernel, where a slab-out-of-bounds splat was reported, similar to a previously reported issue. The fix involves explicitly freeing the route instead of calling
fib6 info release on a half-initialized object. Additionally, the initialization failure of fib6 metrics when the caller provides an nh needs to be taken care of.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
