HIGHCVSS 7/10EPSS 0.37%

Last modified

CVE-2016-10088 is a high-severity vulnerability rated 7/10 on the CVSS scale. 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.. EPSS estimates a 0.37% chance of exploitation in the next 30 days.
