USN-5780-1

It was discovered that a memory leak existed in the IPv6 implementation of the Linux kernel. A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2022-3524)

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)

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)

Tamás Koczka discovered that the Bluetooth L2CAP handshake implementation in the Linux kernel contained multiple use-after-free vulnerabilities. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-42896)
