CVE-2022-0494

Published: 25 March 2022

A kernel information leak flaw was identified in the scsi_ioctl function in drivers/scsi/scsi_ioctl.c in the Linux kernel. This flaw allows a local attacker with a special user privilege (CAP_SYS_ADMIN or CAP_SYS_RAWIO) to create issues with confidentiality.

From the Ubuntu Security Team

It was discovered that the block layer subsystem in the Linux kernel did not properly initialize memory in some situations. A privileged local attacker could use this to expose sensitive information (kernel memory).
