CVE-2022-48947 is a vulnerability in the Linux kernel's Bluetooth L2CAP implementation, affecting Linux kernel versions. It stems from an integer overflow (CWE-190) where repeated L2CAP_CONF_REQ packets can cause the chan->num_conf_rsp counter to wrap around, leading to a denial-of-service condition. Rated with a CVSS score of 5.5 (Medium), this vulnerability has a local attack vector and low attack complexity, requiring local privileges to exploit. The primary impact is high availability loss, with no impact on confidentiality or integrity. There is no evidence of active exploitation, and no public exploit code (Metasploit, Nuclei, ExploitDB) is available. Community discussion and media coverage for this CVE are minimal.
