In the Linux kernel, the following vulnerability has been resolved:
tunnels: fix out of bounds access when building IPv6 PMTU error
If the ICMPv6 error is built from a non-linear skb we get the following splat,
BUG: KASAN: slab-out-of-bounds in docsum+0x220/0x240 Read of size 4 at addr ffff88811d402c80 by task netperf/820 CPU: 0 PID: 820 Comm: netperf Not tainted 6.8.0-rc1+ #543 ... kasanreport+0xd8/0x110 docsum+0x220/0x240 csumpartial+0xc/0x20 skbtunnelcheckpmtu+0xeb9/0x3280 vxlanxmitone+0x14c2/0x4080 vxlanxmit+0xf61/0x5c00 devhardstart_xmit+0xfb/0x510 __devqueuexmit+0x7cd/0x32a0 brdevqueuepushxmit+0x39d/0x6a0
Use skbchecksum instead of csumpartial who cannot deal with non-linear SKBs.
