In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
wifi: rsi: fix heap OOB write on key removal<\/p>\n
When a key is removed (data == NULL), rsi_hal_load_key() runs:<\/p>\n
\tmemset(&set_key[FRAME_DESC_SZ], 0, frame_len – FRAME_DESC_SZ);<\/p>\n
set_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.<\/p>\n
The write fires on every DISABLE_KEY callback, so plain disconnects,
\nroams and interface teardowns trigger it on real networks.<\/p>\n
The 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.<\/p>\n
