Security Bulletin
This security bulletin contains information about 3 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.
MitigationInstall updates from vendor's repository.

2) Out-of-bounds write
EUVDB-ID: #VU63166
Risk: Medium
CVSSv4.0: 4.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2022-1158
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: No
Description The vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due the KVM implementation in Linux kernel does not properly perform guest page table updates in some situations. A remote user on the guest operating system can trigger memory corruption and perform a denial of service attack against the host OS.
Install updates from vendor's repository.
