Description OSIDB Bzimport 2026-08-15 06:26:23 UTC 
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.
