In the Linux kernel, the following vulnerability has been resolved:
net: qrtr: fix 32-bit integer overflow in qrtrendpointpost()
qrtrendpointpost() validates an incoming packet with
if (!size || len != ALIGN(size, 4) + hdrlen)
goto err;
where size comes from the wire. On 32-bit, sizet is 32 bits and ALIGN(size, 4) wraps to 0 for size >= 0xfffffffd, so the check passes and skbput_data(skb, data + hdrlen, size) writes past the hdrlen-sized skb and oopses the kernel. 64-bit is unaffected.
This is the 32-bit residual of ad9d24c9429e2 ("net: qrtr: fix OOB Read in qrtrendpointpost"), which fixed only the 64-bit case.
Reject any size that cannot fit the buffer before the ALIGN.
