CVE-2022-26878

Published: 11 March 2022

drivers/bluetooth/virtio_bt.c in the Linux kernel before 5.16.3 has a memory leak (socket buffers have memory allocated but not freed).

From the Ubuntu Security Team

It was discovered that the VirtIO Bluetooth driver in the Linux kernel did not properly deallocate memory in some error conditions. A local attacker could possibly use this to cause a denial of service (memory exhaustion).

Priority

Medium

CVSS 3 base score: 5.5
