CVE-2026-74341
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.
