Summary
In the Linux kernel, the following vulnerability has been resolved: octeontx2-af: Free BPID bitmap on setup failure nix_setup_bpids() allocates bp->bpids with rvu_alloc_bitmap(), which uses a plain kcalloc(). If any of the following devm_kcalloc() allocations for the BPID mapping arrays fails, the function returns without freeing the bitmap. Free the BPID bitmap before returning from those error paths.
