In the Linux kernel, the following vulnerability has been resolved:

octeontx2-af: fix VF bringup affecting PF promiscuous state

Mbox handling of nix_set_rx_mode for a VF with promiscuous and

all_multi flags set to false causes deletion of the PF's promiscuous

and allmulti MCAM rules. This occurs because the APIs that

enable/disable these rules operate only on the PF, even when the

mbox request is made via a VF interface.

Guard both rvu_npc_enable_allmulti_entry() and

rvu_npc_enable_promisc_entry() disable paths with an is_vf() check so

that a VF bringing up or tearing down its interface cannot inadvertently

clear the PF's MCAM rules. (NVD)
