  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: wcn36xx: fix heap overflow from oversized firmware HAL response\n\nThe firmware response dispatcher copies all synchronous HAL responses\ninto the 4096-byte hal_buf without validating the response length. A\nresponse exceeding WCN36XX_HAL_BUF_SIZE causes a heap buffer overflow\nwith firmware-controlled content.\n\nAdd a bounds check on the response length.",
