Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Double Free
EUVDB-ID: #VU70487
Risk: Low
CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2022-3707
CWE-ID:
CWE-415 - Double Free
Exploit availability: No
DescriptionThe vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error within the intel_gvt_dma_map_guest_page() function in Intel GVT-g graphics driver. A local user can trigger a double free error and crash the kernel.

2) Divide by zero
EUVDB-ID: #VU92736
Risk: Low
CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2023-0615
CWE-ID:
CWE-369 - Divide By Zero
Exploit availability: No
DescriptionThe vulnerability allows a local user to perform a denial of service (DoS) attack.
A memory leak flaw and potential divide by 0 and Integer overflow was found in the Linux kernel V4L2 and vivid test code functionality. This issue occurs when a user triggers ioctls, such as VIDIOC_S_DV_TIMINGS ioctl. This could allow a local user to crash the system if vivid test code enabled.
