CVE-2022-50842

11
FAUCET Score

CVE-2022-50842 is a vulnerability in the Linux kernel's virtio DRM driver, where a missing check for shared memory (shmem) backing of 2D buffer objects could lead to a NULL pointer dereference if userspace provides a VRAM buffer object. While no CVSS score is assigned, the FAUCET Risk Score is 7/100, indicating a low-to-moderate potential impact, likely a denial of service. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage, suggesting it is not widely recognized or exploited in the wild.
