Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 5.5.10
Description
A buffer overflow error was discovered in the
mt76 add fragment function in the Linux kernel, which can be exploited by sending an oversized packet with too many rx fragments, potentially corrupting memory of adjacent pages. This issue may allow an attacker to cause a denial of service and disclose protected information.Recommendations
For Linux kernel versions prior to 5.5.10, update to version 5.5.10 or later to resolve the issue. As a temporary workaround, consider restricting the size of incoming packets to prevent exploitation of the buffer overflow in the
mt76 add fragment function.Fix
