In the Linux kernel, the following vulnerability has been resolved:
net: qrtr: fix OOB Read in qrtr_endpoint_post
Syzbot reported slab-out-of-bounds Read in qrtr_endpoint_post. The problem was in wrong _size_ type:
if (len != ALIGN(size, 4) + hdrlen) goto err;
If size from qrtr_hdr is 4294967293 (0xfffffffd), the result of ALIGN(size, 4) will be 0. In case of len == hdrlen and size == 4294967293 in header this check won't fail and
skb_put_data(skb, data + hdrlen, size);
will read out of bound from data, which is hdrlen allocated block.
