Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Use-after-free
EUVDB-ID: #VU63428
Risk: Low
CVSSv4.0: 5.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2022-1048
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe 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.
MitigationUpdate the affected package the Linux Kernel (Live Patch 0 for SLE 15 SP3) to the latest version.

Q & A
Can this vulnerability be exploited remotely?
No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Incorrect default permissions
EUVDB-ID: #VU63631
Risk: Low
CVSSv4.0: 5.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2022-30594
CWE-ID:
CWE-276 - Incorrect Default Permissions
Exploit availability: No
DescriptionThe 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.
MitigationUpdate the affected package the Linux Kernel (Live Patch 0 for SLE 15 SP3) to the latest version.
