About this tag
The rtl8723bs tag covers security vulnerabilities and fixes in the Linux kernel's staging driver for the Realtek RTL8723BS wireless chipset. Recent discussions focus on three CVEs: CVE-2025-68256 hardens the IE parser against out-of-bounds reads, CVE-2025-68255 fixes a stack buffer overflow in Association Request handling, and CVE-2025-68254 patches an out-of-bounds read in Extended Supported Rates parsing. These issues affect low-power PCs, single-board computers, and embedded devices using SDIO Wi-Fi. The tag is relevant for Linux kernel developers, system administrators, and security researchers tracking driver stability and security updates.
