SUSE update for the Linux Kernel (Live Patch 10 for SLE 15 SP5)

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 10 for SLE 15 SP5) to the latest version.

2) Resource exhaustion

EUVDB-ID: #VU88378

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-52340

CWE-ID: CWE-400 - Resource exhaustion

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to an error when processing very large ICMPv6 packets. A remote attacker can send a flood of IPv6 ICMP6 PTB messages, cause the high lock contention and increased CPU usage, leading to a denial of service.

Successful vulnerability exploitation requires a attacker to be on the local network or have a high bandwidth connection.
