SUSE update for the Linux Kernel (Live Patch 28 for SLE 12 SP5)

1) Use-after-free

EUVDB-ID: #VU63428

Risk: Low

CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-1048

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a local user to execute arbitrary code with elevated privileges.

The vulnerability exists due to a use-after-free error in the Linux kernel’s sound subsystem in the way a user triggers concurrent calls of PCM hw_params. A local user can execute arbitrary code with elevated privileges and perform a denial-of-service attack.

Mitigation

Update the affected package the Linux Kernel (Live Patch 28 for SLE 12 SP5) to the latest version.

2) Incorrect default permissions

EUVDB-ID: #VU63631

Risk: Low

CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-30594

CWE-ID: CWE-276 - Incorrect Default Permissions

Exploit availability: No

Description

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

The vulnerability exists due to mishandling seccomp permissions. A local user can bypass intended restrictions on setting the PT_SUSPEND_SECCOMP flag and escalate privileges on the system.

Mitigation

Update the affected package the Linux Kernel (Live Patch 28 for SLE 12 SP5) to the latest version.
