CVE-2022-49658 is a vulnerability in the Linux kernel's BPF verifier, specifically in the adjust_scalar_min_max_vals function. It allows for insufficient bounds propagation, leading to the potential leakage of pointers by incorrectly turning a pointer register into an unknown scalar. This affects Linux kernel versions. The vulnerability has a CVSS score of 5.5 (Medium), indicating a local attack vector with low attack complexity. A successful exploit could lead to a high impact on availability, though confidentiality and integrity impacts are none. Currently, there is no evidence of active exploitation, and no public exploit code or Metasploit/Nuclei modules are available. Community discussion and media coverage for this CVE are minimal, suggesting low public awareness.
