Cuando se necesita el balanceo de f2fs en la ruta de sincronizaci\u00f3n, se activa el vaciado para quota_release_work. Por defecto, quota_release_work se encola en la cola \u201cevents_unbound\u201d que no tiene la bandera WQ_MEM_RECLAIM. Durante el balanceo de f2fs, la cola de trabajo \u201cwriteback\u201d intenta vaciar quota_release_work, causando un p\u00e1nico del kernel debido a errores de falta de coincidencia de la bandera MEM_RECLAIM.\n\nEste parche crea una cola de trabajo dedicada con la bandera WQ_MEM_RECLAIM para el trabajo quota_release_work.\n\n------------[ cortar aqu\u00ed ]------------\nADVERTENCIA: CPU: 4 PID: 14867 en kernel/workqueue.c:3721 check_flush_dependency+0x13c/0x148\nRastro de llamada:\n check_flush_dependency+0x13c/0x148\n __flush_work+0xd0/0x398\n flush_delayed_work+0x44/0x5c\n dquot_writeback_dquots+0x54/0x318\n f2fs_do_quota_sync+0xb8/0x1a8\n f2fs_write_checkpoint+0x3cc/0x99c\n f2fs_gc+0x190/0x750\n f2fs_balance_fs+0x110/0x168\n f2fs_write_single_data_page+0x474/0x7dc\n f2fs_write_data_pages+0x7d0/0xd0c\n do_writepages+0xe0/0x2f4\n __writeback_single_inode+0x44/0x4ac\n writeback_sb_inodes+0x30c/0x538\n wb_writeback+0xf4/0x440\n wb_workfn+0x128/0x5d4\n process_scheduled_works+0x1c4/0x45c\n worker_thread+0x32c/0x3e8\n kthread+0x11c/0x1b0\n ret_from_fork+0x10/0x20\nP\u00e1nico del kernel - no sincronizando: kernel: panic_on_warn configurado ..."}], "id": "CVE-2025-40196", "lastModified": "2026-11-10T13:17:55.277", "metrics": {}, "published": "2025-11-12T22:15:46.673", "references": [{"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/72b7ceca857f38a8ca7c5629feffc63769638974"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/8a09a62f0c8c6123c2f1864ed6d5f9eb144afaf0"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/8df2eedd371a1c24ecc4283581299d7737dfcd06"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/f12039df1515d5daf7d92e586ece5cefeb39561b"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/f846eacde280ecc3daedfe001580e3033565179e"}, {"source": "0b142b55-0307-4c5a-b3c9-f314f3fb7c5e", "url": "https://cert-portal.siemens.com/productcert/html/ssa-019113.html"}, {"source": "0b142b55-0307-4c5a-b3c9-f314f3fb7c5e", "url": "https://cert-portal.siemens.com/productcert/html/ssa-457936.html"}], "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "vulnStatus": "Deferred"}
