SUSE update for the Linux Kernel (Live Patch 26 for SLE 15 SP3)

1) Buffer overflow

EUVDB-ID: #VU70460

Risk: Low

CVSSv3.1: 6.4 [CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-4139

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error within the i915 kernel driver on Linux kernel. A local user can trigger memory corruption and execute arbitrary code with elevated privileges.

Mitigation

Update the affected package the Linux Kernel (Live Patch 26 for SLE 15 SP3) to the latest version.

2) Stack-based buffer overflow

EUVDB-ID: #VU70442

Risk: Low

CVSSv3.1: 7 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C]

CVE-ID: CVE-2022-4378

CWE-ID: CWE-121 - Stack-based buffer overflow

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error within the __do_proc_dointvec() function. A local user can trigger a stack-based buffer overflow and execute arbitrary code with elevated privileges.

Mitigation

Update the affected package the Linux Kernel (Live Patch 26 for SLE 15 SP3) to the latest version.

3) Buffer overflow

EUVDB-ID: #VU69766

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-2022-43945

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service attacl.

The vulnerability exists due to a boundary error within the Linux kernel NFSD implementation. A remote attacker can send the RPC message over TCP with garbage data added at the end of the message, trigger memory corruption and perform a denial of service (DoS) attack.

Mitigation

Update the affected package the Linux Kernel (Live Patch 26 for SLE 15 SP3) to the latest version.
