Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
wireguard: allowedips: avoid unaligned 64-bit memory accesses<br />
<br />
On the parisc platform, the kernel issues kernel warnings because<br />
swap_endian() tries to load a 128-bit IPv6 address from an unaligned<br />
memory location:<br />
<br />
Kernel: unaligned access to 0x55f4688c in wg_allowedips_insert_v6+0x2c/0x80 [wireguard] (iir 0xf3010df)<br />
Kernel: unaligned access to 0x55f46884 in wg_allowedips_insert_v6+0x38/0x80 [wireguard] (iir 0xf2010dc)<br />
<br />
Avoid such unaligned memory accesses by instead using the<br />
get_unaligned_be64() helper macro.<br />
<br />
[Jason: replace src[8] in original patch with src+8]
