Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Buffer overflow
EUVDB-ID: #VU80048
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-2023-32804
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a local application to escalate privileges on the system.
The vulnerability exists due to a boundary error in Mali GPU Userspace Driver. A local application can trigger memory corruption and execute arbitrary code with elevated privileges.
Install updates from vendor's website.

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) Use-after-free
EUVDB-ID: #VU83835
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-2023-3889
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 caused by improper GPU memory processing operations. A local user can trigger a use-after-free error and execute arbitrary code on the system.
