Description

The sg_ioctl function in drivers/scsi/sg.c in the Linux kernel through 4.10.4 allows local users to cause a denial of service (stack-based buffer overflow) or possibly have unspecified other impact via a large command size in an SG_NEXT_CMD_LEN ioctl call, leading to out-of-bounds write access in the sg_write function.

Affected configurations

• linux linux kernel (< 3.18.50) • linux linux kernel (>= 3.19 < 4.1.40) • linux linux kernel (>= 4.2 < 4.4.60) • linux linux kernel (>= 4.5 < 4.9.21) • linux linux kernel (>= 4.10 < 4.10.9)
