Name of the Vulnerable Software and Affected Versions Linux kernel versions through 4.9

Description The sg implementation in the Linux kernel does not properly restrict write operations in situations where the KERNEL DS option is set, allowing local users to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging access to a /dev/sg device, related to block/bsg.c and drivers/scsi/sg.c.

Recommendations For Linux kernel versions through 4.9, update to a version later than 4.9 to resolve the issue. As a temporary workaround, consider restricting access to the /dev/sg device to minimize the risk of exploitation.
