Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Use-after-free
EUVDB-ID: #VU61097
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-2021-39698
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error in Linux kernel. A local user can run a specially crafted program to trigger the use-after-free error and execute arbitrary code with elevated privileges.
Update the affected package the Linux Kernel (Live Patch 31 for SLE 15 SP2) to the latest version.

2) Permissions, Privileges, and Access Controls
EUVDB-ID: #VU68110
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-2022-39189
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe vulnerability allows a guest user to escalate privileges on the system.
The vulnerability exists due to incorrect handling of TLB flush operations in certain KVM_VCPU_PREEMPTED situations in the x86 KVM subsystem in the Linux kernel. An attacker with unprivileged access to the guest OS can escalate privileges on the guest.
Update the affected package the Linux Kernel (Live Patch 31 for SLE 15 SP2) to the latest version.
