Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Buffer overflow
EUVDB-ID: #VU60988
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-2022-0330
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a random memory access flaw caused by a missing TLB flush in Linux kernel GPU i915 kernel driver functionality. A local user can execute arbitrary code on the system with elevated privileges.
Update the affected package the Linux Kernel (Live Patch 23 for SLE 15 SP2) to the latest version.

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.
Update the affected package the Linux Kernel (Live Patch 23 for SLE 15 SP2) to the latest version.
