Realtek RTL8723BS Driver for Linux Hardened Against Malicious Wi-Fi Access Points
Translated by a model; the original is in Russian.
Linux kernel developers have put together a set of fixes for the staging drivers that will land ahead of the Linux 7.2-rc3 release. The bulk of this batch consists of improvements to the Realtek RTL8723BS driver, which provides support for the Wi-Fi chip of the same name.
What changed
Most of the fixes address out-of-bounds behavior that occurs when a device connects to “bad” Wi-Fi access points. Such bugs could potentially allow a malicious access point to trigger faulty behavior in the driver on the client side.
Why it matters
The RTL8723BS is a widely used chip found in many single-board computers and inexpensive devices, where it handles wireless connectivity. Its driver has long resided in the Linux kernel's staging tree, meaning it is still being refined before being moved into the main part of the codebase. Fixing vulnerabilities like these reduces the risk of attacks through malicious Wi-Fi infrastructure against devices that use this chip.
The fixes will be included in the Linux 7.2-rc3 release candidate.
