CVE-2021-3483 is a significant vulnerability identified in the Linux kernel, specifically within two of its modules: the f2fs module and the bluetooth subsystem. This flaw is essentially a software design or implementation error that exposes the system to potential security breaches. The first issue was an out-of-bounds (OOB) memory access flaw in the f2fs module, which could lead to unauthorized data access or system crashes due to memory corruption. The second part of CVE-2021-3483 pertains to the Bluetooth subsystem in the Linux kernel. It was found that this subsystem did not adequately handle HCI device initialization failure, resulting in a double-free vulnerability. This kind of vulnerability can lead to memory corruption, potentially enabling attackers to execute arbitrary code or cause a denial of service. This vulnerability, CVE-2021-3483, is part of a larger set of Common Vulnerabilities and Exposures (CVEs) mentioned in the United States National (USN) advisory, including but not limited to: CVE-2021-28660, CVE-2021-28964, CVE-2020-25672, CVE-2021-28972, CVE-2021-29647, CVE-2021-3483, CVE-2021-28971, CVE-2020-25670, CVE-2021-31916, CVE-2020-25671, CVE-2020-25673, CVE-2021-3428, and CVE-2021-33033. These vulnerabilities highlight the need for continuous monitoring and timely patching of systems to maintain their security.
