Upgrade SLES:15.2 kernel-livepatch-5_3_18-24_67-default to version 5-2.1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-5_3_18-24_67-default package and not the kernel-livepatch-5_3_18-24_67-default package as distributed by SLES.
See How to fix? for SLES:15.2 relevant fixed versions and status.
In drivers/char/virtio_console.c in the Linux kernel before 5.13.4, data corruption or loss can be triggered by an untrusted device that supplies a buf->len value exceeding the buffer size. NOTE: the vendor indicates that the cited data corruption is not a vulnerability in any existing use case; the length validation was added solely for robustness in the face of anomalous host OS behavior
