USN-5850-1: Linux kernel vulnerabilities

Published Feb 9, 2023
·
Updated

It was discovered that the Bluetooth HCI implementation in the Linux kernel did not properly deallocate memory in some situations. An attacker could possibly use this cause a denial of service (memory exhaustion). (CVE-2022-3619) It was discovered that the Broadcom FullMAC USB WiFi driver in the Linux kernel did not properly perform bounds checking in some situations. A physically proximate attacker could use this to craft a malicious USB device that when inserted, could cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-3628) It was discovered that a use-after-free vulnerability existed in the Bluetooth stack in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-3640) Tamás Koczka discovered that the Bluetooth L2CAP implementation in the Linux kernel did not properly initialize memory in some situations. A physically proximate attacker could possibly use this to expose sensitive information (kernel memory). (CVE-2022-42895) It was discovered that a race condition existed in the qdisc implementation in 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-2023-0590)
