CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's handling of firmware responses in the wcn36xx driver, where an oversized HAL response can lead to a heap buffer overflow due to insufficient validation of response length. This flaw could allow an attacker to exploit the overflow with malicious firmware content, potentially leading to arbitrary code execution or system instability. Organizations using affected Linux systems, particularly those relying on WCN36XX hardware, should prioritize applying the patch to mitigate the risk of exploitation.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: wifi: wcn36xx: fix heap overflow from oversized firmware HAL response The firmware response dispatcher copies all synchronous HAL responses into the 4096-byte hal_buf without validating the response length. A response exceeding WCN36XX_HAL_BUF_SIZE causes a heap buffer overflow with firmware-controlled content. Add a bounds check on the response length.
