SUSE update for the Linux Kernel (Live Patch 25 for SLE 15 SP4)

1) Out-of-bounds read

EUVDB-ID: #VU89680

Risk: Medium

CVSSv3.1: 4.7 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-48651

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 in drivers/net/ipvlan/ipvlan_core.c. A remote attacker on the local network can send specially crafted packets to the system, trigger an out-of-bounds read error and read contents of memory on the system.

Mitigation

Update the affected package the Linux Kernel (Live Patch 25 for SLE 15 SP4) to the latest version.
