| In the Linux kernel, the following vulnerability has been resolved:
crypto: ccp - Fix snp_filter_reserved_mem_regions() off-by-one
Sashiko notes:
> regarding the bounds check in snp_filter_reserved_mem_regions()
> called via walk_iomem_res_desc(): does the check
> if ((range_list->num_elements * 16 + 8) > PAGE_SIZE)
> allow an off-by-one heap buffer overflow?
>
> If range_list->num_elements is 255, 255 * 16 + 8 = 4088, which is <= 4096.
> Writing range->base (8 bytes) fills 4088-4095, but writing range->page_count
> (4 bytes) would write to 4096-4099, overflowing the kzalloc-allocated
> PAGE_SIZE buffer.
Fix this by accounting for the entry about to be written to, in addition to
the entries that are already allocated. |
| In the Linux kernel, the following vulnerability has been resolved:
octeontx2-af: Block VFs from clobbering special CGX PKIND state
PF and VF NIX LFs that share a CGX LMAC reuse the same hardware PKIND
programming. When HiGig2 or EDSA parsing is enabled, a VF NIX LF alloc must
not reset the LMAC RX PKIND or default TX parse config over the PF setup.
Add cgx_get_pkind() and rvu_cgx_is_pkind_config_permitted() so VFs skip
cgx_set_pkind(), rvu_npc_set_pkind(), and NIX_AF_LFX_TX_PARSE_CFG updates
when the LMAC is using NPC_RX_HIGIG_PKIND or NPC_RX_EDSA_PKIND. |
