CVE-2022-36648 - QEMU UP TO 7.0.0 ROCKER DEVICE

The hardware emulation in the of_dpa_cmd_add_l2_flood of rocker device model in QEMU, as used in 7.0.0 and earlier, allows remote attackers to crash the host qemu and potentially execute code on the host via execute a malformed program in the guest OS.

PVE 7.4 is on QEMU 7.2.0.

But, of course, you want to wait for an answer from a Proxmox developer to be absolutely sure.
if you haven't added it explicitly via the custom arguments switch -args "-device rocker,<...>", the rocker device is not used by Proxmox VE.
