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.","published":"2026-01-13T16:16:09.000Z","lastModified":"2026-10-15T02:18:19.000Z","status":"Modified","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":{"version":"3.1","score":5.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},"cwe":[],"affected":["linux/linux kernel"],"epss":{"score":0.00293,"percentile":0.21747,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.29%).
