  "summary": "wifi: rsi: fix heap OOB write on key removal",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: rsi: fix heap OOB write on key removal\n\nWhen a key is removed (data == NULL), rsi_hal_load_key() runs:\n\n\tmemset(&set_key[FRAME_DESC_SZ], 0, frame_len - FRAME_DESC_SZ);\n\nset_key is a struct rsi_set_key *, so the subscript is scaled by\nsizeof(struct rsi_set_key) (160 bytes): &set_key[FRAME_DESC_SZ] is\nskb->data + 2560, and the memset writes 144 zero bytes starting\n2.4KB past the end of the 160-byte skb data buffer, corrupting\nunrelated heap objects. The intended byte offset would have been\n(u8 *)set_key + FRAME_DESC_SZ.\n\nThe write fires on every DISABLE_KEY callback, so plain disconnects,\nroams and interface teardowns trigger it on real networks.\n\nThe memset is redundant: the whole buffer is zeroed right after\nallocation, so the frame sent to the device is byte-identical\nwithout it. Drop the else branch; normal operation is unaffected.\n\nDiscovered by Atuin - Automated Vulnerability Discovery Engine.",
