{"id":"CVE-2025-68321","summary":"page_pool: always add GFP_NOWARN for ATOMIC allocations","details":"In the Linux kernel, the following vulnerability has been resolved:\n\npage_pool: always add GFP_NOWARN for ATOMIC allocations\n\nDriver authors often forget to add GFP_NOWARN for page allocation\nfrom the datapath. This is annoying to users as OOMs are a fact\nof life, and we pretty much expect network Rx to hit page allocation\nfailures during OOM. Make page pool add GFP_NOWARN for ATOMIC allocations\nby default.","modified":"2026-04-02T13:03:34.417298Z","published":"2025-12-16T15:44:19.066Z","related":["MGASA-2026-0017","MGASA-2026-0018"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/68xxx/CVE-2025-68321.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0ec2cd5c58793d0c622797cd5fbe26634b357210"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3671a0775952026228ae44e096eb144bca75f8dc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7613c06ffa89c1e2266fb532e23ef7dfdf269d73"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9835a0fd59a1df5ec0740fdab6d50db68e0f10de"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ab48dc0e23eb714b3f233f8e8f6deed7df2051f5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f3b52167a0cb23b27414452fbc1278da2ee884fc"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/68xxx/CVE-2025-68321.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-68321"},{"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":"ff7d6b27f894f1469dc51ccb828b7363ccd9799f"},{"fixed":"0ec2cd5c58793d0c622797cd5fbe26634b357210"},{"fixed":"9835a0fd59a1df5ec0740fdab6d50db68e0f10de"},{"fixed":"7613c06ffa89c1e2266fb532e23ef7dfdf269d73"},{"fixed":"3671a0775952026228ae44e096eb144bca75f8dc"},{"fixed":"ab48dc0e23eb714b3f233f8e8f6deed7df2051f5"},{"fixed":"f3b52167a0cb23b27414452fbc1278da2ee884fc"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-68321.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.18.0"},{"fixed":"5.15.197"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.159"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.117"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.58"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.17.8"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-68321.json"}}],"schema_version":"1.7.5"}
