{"id":"USN-5267-3","summary":"linux-raspi, linux-raspi-5.4 vulnerabilities","details":"USN-5267-1 fixed vulnerabilities in the Linux kernel. This update\nprovides the corresponding updates for the Linux kernel for Raspberry\nPi devices.\n\nOriginal advisory details:\n\n It was discovered that the Bluetooth subsystem in the Linux kernel\n contained a use-after-free vulnerability. A local attacker could use this\n to cause a denial of service (system crash) or possibly execute arbitrary\n code. (CVE-2021-3640)\n\n Likang Luo discovered that a race condition existed in the Bluetooth\n subsystem of the Linux kernel, leading to a use-after-free vulnerability. A\n local attacker could use this to cause a denial of service (system crash)\n or possibly execute arbitrary code. (CVE-2021-3752)\n\n Luo Likang discovered that the FireDTV Firewire driver in the Linux kernel\n did not properly perform bounds checking in some situations. A local\n attacker could use this to cause a denial of service (system crash) or\n possibly execute arbitrary code.
