Linux · Linux Kernel · CVE-2019-17666
**Name of the Vulnerable Software and Affected Versions**
Linux kernel versions through 5.3.6
**Description**
The issue is related to a buffer overflow in the `rtl p2p noa ie` function in the Linux kernel's `rtlwifi` driver. This vulnerability can be exploited remotely, allowing an attacker to access confidential data, compromise its integrity, and cause a denial of service. The vulnerability is associated with a lack of a certain upper-bound check, leading to a buffer overflow. It can be exploited by sending specially crafted frames, potentially allowing code execution in the context of the kernel.
**Recommendations**
For Linux kernel versions through 5.3.6, update to a version that includes the fix for this issue. As a temporary workaround, consider restricting access to the `rtlwifi` driver to minimize the risk of exploitation. Avoid using the `rtl p2p noa ie` function until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability, but a patch has been proposed by Nicolas Waisman, a security engineer at GitHub.
