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

octeontx2-af: cn10k: restrict VF LMTLINE sharing to its own PF

rvu_mbox_handler_lmtst_tbl_setup() uses req->base_pcifunc as a direct

index into the LMT map table to read another function's LMTLINE

physical base address and copy it into the caller's own LMT map table

entry. The mailbox dispatcher authenticates req->hdr.pcifunc from the

IRQ source, but req->base_pcifunc is a separate payload field and is

not sanitized.

Reject the request with -EPERM when a VF caller's base_pcifunc is not a

valid function under its own PF. is_pf_func_valid() bounds the FUNC field

to the PF's configured VF count, keeping the computed index inside the

caller's own slot block. (NVD)
