GHSA-m9p4-r7pw-hpw3

GHSA-m9p4-r7pw-hpw3 PUBLISHED CVSS 7 HIGH

Record from GitHub Advisory Database · Published May 14, 2022

The sg implementation in the Linux kernel through 4.9 does not properly restrict write operations in situations where the KERNEL_DS option is set, which allows 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. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-9576.
