This is incorrect since the\ndpaa2_switch_free_fd() is intended to be used on Tx frame descriptors,\nmeaning that it expects in the software annotation area of the FD data\nto find a valid skb pointer on which to call dev_kfree_skb().\n\nFix this by extracting the dma_unmap_page() from\ndpaa2_switch_build_linear_skb() directly into the dpaa2_switch_rx()\nfunction. This allows us to directly use free_pages() in case of an\nerror before an SKB was created and kfree_skb() afterwards.","state":0,"publishedAt":"2026-10-23T11:54:57.029+00:00","modifiedAt":"2026-10-23T11:54:57.029+00:00","affected":[{"ecosystem":"Vendor
