{"schema":"threatline.record/2","record":{"id":"CVE-2026-98911","aliases":[],"summary":"dpaa2-switch: fix the error path in dpaa2_switch_rx()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndpaa2-switch: fix the error path in dpaa2_switch_rx()\n\nIn case of an error in dpaa2_switch_rx(), the dpaa2_switch_free_fd()\nfunction is called in order to free the FD. 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.","categories":["Operating
