CVE-2022-49219

17
FAUCET Score

CVE-2022-49219 is a memory leak vulnerability in the Linux kernel's vfio/pci driver. It occurs during D3hot to D0 power state transitions when specific reset-related IOCTLs are used, preventing the proper freeing of allocated memory. This can lead to an Out-Of-Memory (OOM) condition if a malicious actor repeatedly triggers the state change. The vulnerability has a CVSS score of 5.5 (Medium), indicating a local attack vector with low complexity and a high impact on availability. While it can lead to a denial of service, it does not affect confidentiality or integrity. Currently, there is no evidence of active exploitation, and no public exploit code (Metasploit, Nuclei, ExploitDB) or significant community discussion has been observed for this CVE.
