Description
Stack-based buffer overflow in the run_init_sbus function in the KCodes NetUSB module for the Linux kernel, as used in certain NETGEAR products, TP-LINK products, and other products, allows remote attackers to execute arbitrary code by providing a long computer name in a session on TCP port 20005.
Public exploits
Exploit or proof-of-concept code for this vulnerability is publicly available, which lowers the bar for attackers. Treat it as a reason to patch sooner.
Third-party code, not reviewed by us. Public PoCs are sometimes fake or contain malware. Read the code first and run it only in an isolated lab, against systems you are authorised to test.
