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:

memset(&set_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): &set_key[FRAME_DESC_SZ] is skb->data + 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 + 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.
