Original advisory details:

 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)");
