CVE-2021-47291

CVSS v3.1

7.1

High

VectorAV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H
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.
