CVE-2020-12770

Published: 9 May 2020

An issue was discovered in the Linux kernel through 5.6.11. sg_write lacks an sg_remove_request call in a certain failure case, aka CID-83c6f2390040.

From the Ubuntu security team

It was discovered that the SCSI generic (sg) driver in the Linux kernel did not properly handle certain error conditions correctly. A local privileged attacker could use this to cause a denial of service (system crash).

Priority
