Published: Translated: NVD NIST

Summary

The sg_ioctl function in the Linux kernel through version 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.

Risk Assessment

This vulnerability may lead to denial of service, affecting system availability. There is also a risk of unspecified impact on the system, which could lead to further security issues.

Recommendation

It is recommended to update the Linux kernel to version 4.10.5 or later to mitigate this vulnerability. Additionally, monitor systems for unauthorized actions by local users.
