CVE-2023-29468 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. The Texas Instruments (TI) WiLink WL18xx MCP driver does not limit the number of information elements (IEs) of type XCC_EXT_1_IE_ID or XCC_EXT_2_IE_ID that can be parsed in a management frame. Using a specially crafted frame, a buffer overflow can be triggered that can potentially lead to remote code execution. EPSS estimates a 10.08% chance of exploitation in the next 30 days.
