Lifecycle Timeline
1DescriptionNVD
A Red Hat only CVE-2020-12351 regression issue was found in the way the Linux kernel's Bluetooth implementation handled L2CAP packets with A2MP CID. This flaw allows a remote attacker in an adjacent range to crash the system, causing a denial of service or potentially executing arbitrary code on the system by sending a specially crafted L2CAP packet. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
AnalysisAI
A Red Hat only CVE-2020-12351 regression issue was found in the way the Linux kernel's Bluetooth implementation handled L2CAP packets with A2MP CID. Rated high severity (CVSS 8.8), this vulnerability is no authentication required, low attack complexity. No vendor patch available.
Technical ContextAI
This vulnerability is classified as Access of Resource Using Incompatible Type (Type Confusion) (CWE-843), which allows attackers to execute arbitrary code by exploiting type confusion in the application. A Red Hat only CVE-2020-12351 regression issue was found in the way the Linux kernel's Bluetooth implementation handled L2CAP packets with A2MP CID. This flaw allows a remote attacker in an adjacent range to crash the system, causing a denial of service or potentially executing arbitrary code on the system by sending a specially crafted L2CAP packet. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. Affected products include: Redhat Enterprise Linux.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Enforce strict type checking, use type-safe languages, validate object types before operations.
