CVE-2018-19985
CVSS v2.0
4.9
Média
| Vetor | AV:L/AC:L/Au:N/C:C/I:N/A:N |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 4.19.9
Description
The issue is related to the function
hso get config data in the Linux kernel, which reads data from a USB device and uses it to index an array. This can result in an object out-of-bounds read, potentially allowing arbitrary read access in the kernel address space. The vulnerability may be exploited to cause a denial of service.Recommendations
For Linux kernel versions prior to 4.19.9, update to version 4.19.9 or later to resolve the issue. As a temporary workaround, consider restricting access to the
hso get config data function in the drivers/net/usb/hso.c file until a patch is available.Correção
Out of bounds Read
