  "title": "wifi: rsi: fix heap OOB write on key removal",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  wifi: rsi: fix heap OOB write on key removal  When a key is removed (data == NULL), rsi_hal_load_key() runs:  \tmemset(\u0026set_key[FRAME_DESC_SZ], 0, frame_len - FRAME_DESC_SZ);  set_key is a struct rsi_set_key *, so the subscript is scaled by sizeof(struct rsi_set_key) (160 bytes): \u0026set_key[FRAME_DESC_SZ] is skb-\u003Edata \u002B 2560, and the memset writes 144 zero bytes starting 2.4KB past the end of the 160-byte skb data buffer, corrupting unrelated heap objects. The intended byte offset would have been (u8 *)set_key \u002B FRAME_DESC_SZ.  The write fires on every DISABLE_KEY callback, so plain disconnects, roams and interface teardowns trigger it on real networks.  The memset is redundant: the whole buffer is zeroed right after allocation, so the frame sent to the device is byte-identical without it. Drop the else branch; normal operation is unaffected.  Discovered by Atuin - Automated Vulnerability Discovery Engine.",
