{"id":"CVE-2026-98911","published":"2026-10-23T12:18:25.240","lastModified":"2026-10-26T07:17:16.467","description":"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.","cvssScore":7.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/259ad6093204b999d41e7e6d0ad90ef9a71a44ab","tags":[]},{"url":"https://git.kernel.org/stable/c/74c1c9f5c0c30bbd0c2cf87b6e3507e7ea46c13d","tags":[]},{"url":"https://git.kernel.org/stable/c/791068c962469af0090e1a1ee63657fb9eef40db","tags":[]},{"url":"https://git.kernel.org/stable/c/ee54f8d7e642c44cfcc2dcb390b4c50e145d81b8","tags":[]},{"url":"https://git.kernel.org/stable/c/f4ceb8e3d6d5becb4cda7a7098a8638e18c835a1","tags":[]},{"url":"https://git.kernel.org/stable/c/fa232b4496cb59503ae5108c756cbe10e59b0bc3","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
