Security Bulletin
This security bulletin contains information about 3 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 4 for SLE 15 SP3) to the latest version.

No. We are not aware of malware exploiting this vulnerability.
2) Permissions, Privileges, and Access Controls
EUVDB-ID: #VU61217
Risk: Low
CVSSv4.0: 8.5 [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:A/U:Clear]
CVE-ID: CVE-2022-22942
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: Yes
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to an error in the vmwgfx driver in Linux kernel. A local unprivileged user can gain access to files opened by other processes on the system through a dangling 'file' pointer.
Exploiting this vulnerability requires an attacker to have access to either /dev/dri/card0 or /dev/dri/rendererD128 and be able to issue an ioctl() on the resulting file descriptor.
Update the affected package the Linux Kernel (Live Patch 4 for SLE 15 SP3) to the latest version.

3) Heap-based buffer overflow
EUVDB-ID: #VU61672
Risk: Low
CVSSv4.0: 6.4 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear]
CVE-ID: CVE-2022-27666
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: Yes
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error within IPsec ESP transformation code in net/ipv4/esp4.c and net/ipv6/esp6.c in Linux kernel. A local unprivileged user can pass specially crafted data to the system, trigger a heap-based buffer overflow and execute arbitrary code with elevated privileges.
Update the affected package the Linux Kernel (Live Patch 4 for SLE 15 SP3) to the latest version.
