Keyu Man discovered that the ICMP implementation in the Linux kernel did not properly handle received ICMP error packets. A remote attacker could use this to facilitate attacks on UDP based services that depend on source port randomization. (CVE-2021-20322) It was discovered that the Bluetooth subsystem in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-3640) Likang Luo discovered that a race condition existed in the Bluetooth subsystem of the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-3752) Luo Likang discovered that the FireDTV Firewire driver in the Linux kernel did not properly perform bounds checking in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-42739)
