Описание
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.
A vulnerability was found in sg_write in drivers/scsi/sg.c in the SCSI generic (sg) driver subsystem. This flaw allows an attacker with local access and special user or root privileges to cause a denial of service if the allocated list is not cleaned with an invalid (Sg_fd * sfp) pointer at the time of failure, also possibly causing a kernel internal information leak problem.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
