The staging driver fixes that were sent out this week ahead of the Linux 7.2-rc3 release is predominantly made up of hardening the Realtek RTL8723BS WiFi driver. In particular, a number of fixes for addressing out-of-bounds behavior when connecting to “bad” WiFi hosts.<\/p>\n

Alexandru Hossu has been working on addressing a number of out-of-bounds “OOB” memory access conditions that could occur when the driver is iterating on attacker-controlled data provided from over-the-air frames. The driver was not properly validating the header or payload that could lead to a number of OOB reads\/writes if connecting to a malicious WiFi access point.\n<\/p>\n

These patches are set to be merged today ahead of the Linux 7.2-rc3 kernel release. These security fixes are also set to be back-ported to the existing Linux stable kernel versions too. These security shortcomings around over-the-air WiFi data handling have existed since the rtl8723bs driver was added to the Linux kernel’s staging area back in 2017.

Since the staging admission nearly a decade ago, the Realtek RTL8723BS has continued seeing much driver cleaning with nearly ever kernel cycle with it proving to be a “beast of a driver” in code complexity. The Realtek RTL8723BS is an 802.11 b\/g\/n SDIO WiFi chipset with Bluetooth 4.0 support and over the years has been found in many different devices. <\/p>\n

These out-of-bounds fixes when dealing with nefarious WiFi hosts is the main set of changes with this week’s staging fixes.<\/p>\n
