Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Double Free
EUVDB-ID: #VU63766
Risk: High
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:Amber]
CVE-ID: CVE-2021-22600
CWE-ID:
CWE-415 - Double Free
Exploit availability: Yes
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error in the packet_set_ring() function in net/packet/af_packet.c. A local user can pass specially crafted data to the application, trigger double free error and escalate privileges on the system.
Note, the vulnerability is being actively exploited in the wild against Android users.
Install updates from vendor's repository.

Is there known malware, which exploits this vulnerability?
Yes. This vulnerability is being exploited in the wild.
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.
Install updates from vendor's repository.
