The memory type of the resulting xdp_frame\ndepends on the memory type of the xdp_buff. For page pool based xdp_buff\nit produces xdp_frame with memory type MEM_TYPE_PAGE_POOL. For zero copy\nXSK pool based xdp_buff it produces xdp_frame with memory type\nMEM_TYPE_PAGE_ORDER0. However, stmmac_xdp_xmit_back() does not check the\nmemory type and always uses the page pool type, this leads to invalid\nmappings and causes the crash. Therefore, check the xdp_buff memory type\nin stmmac_xdp_xmit_back() to fix this issue.","modified":"2026-04-02T13:04:46.272442Z","published":"2026-01-13T15:34:55.392Z","related":["MGASA-2026-0017","MGASA-2026-0018","SUSE-SU-2026:0447-1","SUSE-SU-2026:0472-1","SUSE-SU-2026:0587-1","SUSE-SU-2026:20477-1","SUSE-SU-2026:20498-1","SUSE-SU-2026:20555-1","SUSE-SU-2026:20599-1","SUSE-SU-2026:20615-1","SUSE-SU-2026:20845-1","SUSE-SU-2026:20876-1","openSUSE-SU-2026:20287-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/71xxx/CVE-2025-71095.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/3f7823219407f2f18044c2b72366a48810c5c821"},{"type":"WEB","url":"https://git.kernel.org/stable/c/45ee0462b88396a0bd1df1991f801c89994ea72b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4d0ceb7677e1c4616afb96abb4518f70b65abb0d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5e5988736a95b1de7f91b10ac2575454b70e4897"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a48e232210009be50591fdea8ba7c07b0f566a13"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/71xxx/CVE-2025-71095.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-71095"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"bba2556efad66e7eaa56fece13f7708caa1187f8"},{"fixed":"3f7823219407f2f18044c2b72366a48810c5c821"},{"fixed":"4d0ceb7677e1c4616afb96abb4518f70b65abb0d"},{"fixed":"45ee0462b88396a0bd1df1991f801c89994ea72b"},{"fixed":"5e5988736a95b1de7f91b10ac2575454b70e4897"},{"fixed":"a48e232210009be50591fdea8ba7c07b0f566a13"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-71095.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.13.0"},{"fixed":"6.1.160"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.120"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.64"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-71095.json"}}],"schema_version":"1.7.5"}
