CVE-2023-25525
NVIDIA Cumulus Linux contains a vulnerability in forwarding where a VxLAN-encapsulated IPv6 packet received on an SVI interface with DMAC/DIPv6 set to the link-local address of the SVI interface may be incorrectly forwarded.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.55%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
