{"id":"CVE-2025-37859","summary":"page_pool: avoid infinite loop to schedule delayed worker","details":"In the Linux kernel, the following vulnerability has been resolved:\n\npage_pool: avoid infinite loop to schedule delayed worker\n\nWe noticed the kworker in page_pool_release_retry() was waken\nup repeatedly and infinitely in production because of the\nbuggy driver causing the inflight less than 0 and warning\nus in page_pool_inflight()[1].\n\nSince the inflight value goes negative, it means we should\nnot expect the whole page_pool to get back to work normally.\n\nThis patch mitigates the adverse effect by not rescheduling\nthe kworker when detecting the inflight negative in\npage_pool_release_retry().\n\n[1]\n[Mon Feb 10 20:36:11 2025] ------------[ cut here ]------------\n[Mon Feb 10 20:36:11 2025] Negative(-51446) inflight packet-pages\n...\n[Mon Feb 10 20:36:11 2025] Call Trace:\n[Mon Feb 10 20:36:11 2025]  page_pool_release_retry+0x23/0x70\n[Mon Feb 10 20:36:11 2025]  process_one_work+0x1b1/0x370\n[Mon Feb 10 20:36:11 2025]  worker_thread+0x37/0x3a0\n[Mon Feb 10 20:36:11 2025]  kthread+0x11a/0x140\n[Mon Feb 10 20:36:11 2025]  ? process_one_work+0x370/0x370\n[Mon Feb 10 20:36:11 2025]  ? __kthread_cancel_work+0x40/0x40\n[Mon Feb 10 20:36:11 2025]  ret_from_fork+0x35/0x40\n[Mon Feb 10 20:36:11 2025] ---[ end trace ebffe800f33e7e34 ]---\nNote: before this patch, the above calltrace would flood the\ndmesg due to repeated reschedule of release_dw kworker.","modified":"2026-05-15T11:53:51.252627193Z","published":"2025-05-09T06:42:06.596Z","related":["SUSE-SU-2025:02249-1","SUSE-SU-2025:02254-1","SUSE-SU-2025:02307-1","SUSE-SU-2025:02333-1","SUSE-SU-2025:02335-1","SUSE-SU-2025:02538-1","SUSE-SU-2025:02923-1","SUSE-SU-2025:20475-1","SUSE-SU-2025:20483-1","SUSE-SU-2025:20493-1","SUSE-SU-2025:20498-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/37xxx/CVE-2025-37859.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/43130d02baa137033c25297aaae95fd0edc41654"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7204335d1991c23fc615ab76f31f175748a578e1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/738d1812ec2e395e953258aea912ddd867d11a13"},{"type":"WEB","url":"https://git.kernel.org/stable/c/90e089a64504982f8d62f223027cb9f903781f78"},{"type":"WEB","url":"https://git.kernel.org/stable/c/91522aba56e9fcdf64da25ffef9b27f8fad48e0f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/95f17738b86fd198924d874a5639bcdc49c7e5b8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9f71db4fb82deb889e0bac4a51b34daea7d506a3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c3c7c57017ce1d4b2d3788c1fc59e7e39026e158"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e74e5aa33228c5e2cb4fc80ad103541a7b7805ec"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/05/msg00030.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/05/msg00045.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/37xxx/CVE-2025-37859.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-37859"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.4.293"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.5.0"},{"fixed":"5.10.237"},{"fixed":"5.15.181"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"6.1.135"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.6.88"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.12.24"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.13.12"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.14.3"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2025-37859.json"}}],"schema_version":"1.7.5"}
