CVE-2022-50822

11
FAUCET Score

CVE-2022-50822 is a memory leak vulnerability in the Linux kernel's RDMA subsystem, specifically within the restrack module, which occurs when a Memory Region (MR) restrack is deleted but not properly released. This oversight can lead to memory exhaustion as the associated task struct remains allocated. While a CVSS score is unavailable, its FAUCET Risk Score is low at 7/100, and its EPSS score is minimal, suggesting a low probability of exploitation. There is currently no evidence of active exploitation, public exploit code, or significant community discussion or media coverage surrounding this vulnerability.
