SUSE update for the Linux Kernel (Live Patch 43 for SLE 15 SP3)

1) Out-of-bounds read

EUVDB-ID: #VU88889

Risk: Medium

CVSSv3.1: 4.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2021-46955

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition within the ovs_fragment() function in net/openvswitch/actions.c when running openvswitch on kernels built with KASAN. A remote attacker can send specially crafted IPv4 packets to the system, trigger an out-of-bounds read error and read contents of memory on the system or crash the kernel.

Mitigation

Update the affected package the Linux Kernel (Live Patch 43 for SLE 15 SP3) to the latest version.
