Desde el commit 9f86d624292c (\"mm/damon/vaddr-test: eliminar variables innecesarias\"), damon_destroy_ctx() se elimina, pero a\u00fan se llama a damon_new_target() y damon_new_region(), la damon_region asignada por kmem_cache_alloc() en damon_new_region() y el damon_target asignado por kmalloc en damon_new_target() no se libera. Y el damon_region que est\u00e1 asignado en damon_new_region() en damon_set_regions() tampoco se libera. Entonces use damon_destroy_target para liberar todos los damon_regions y damon_target. objeto sin referencia 0xffff888107c9a940 (tama\u00f1o 64): comm \"kunit_try_catch\", pid 1069, jiffies 4294670592 (edad 732,761 s) volcado hexadecimal (primeros 32 bytes): 00 00 00 00 00 00 00 00 06 00 00 00 6b 6b 6b 6b... .........kkkk 60 c7 9c 07 81 88 ff ff f8 cb 9c 07 81 88 ff ff `................. backtrace: [] kmalloc_trace +0x27/0xa0 [] damon_new_target+0x3f/0x1b0 [] damon_do_test_apply_tres_regiones.constprop.0+0x95/0x3e0 [] damon_test_apply_tres_regiones1+0x21e/ 0x260 [] kunit_generic_run_threadfn_adapter+0x4a/0x90 [&lt; ffffffff81237cf6&gt;] kthread+0x2b6/0x380 [] ret_from_fork+0x2d/0x70 [] ret_from_fork_asm+0x11/0x20 objeto sin referencia 0xffff8881079cc740 (tama\u00f1o 56): comm \"kunit_try_catch\", pid 1069, santiam\u00e9n 4294670592 (edad 732,761 s ) volcado hexadecimal (primeros 32 bytes): 05 00 00 00 00 00 00 00 14 00 00 00 00 00 00 00 ................ 6b 6b 6b 6b 6b 6b 6b 6b 00 00 00 00 6b 6b 6b 6b kkkkkkkk....kkkk retroceso: [] damon_new_region+0x22/0x1c0 [] damon_do_test_apply_tres_regiones.constprop.0+0xd1/0x3e0 [] damon_test_apply_tres_regiones1+0x21e/0x260 [ ] kunit_generic_run_threadfn_adapter+0x4a/0x90 [] kthread+0x2b6/0x380 [] ret_from_fork+0x2d/0x70 [] ret_from_ fork_asm+0x11/0x20 objeto sin referencia 0xffff888107c9ac40 (tama\u00f1o 64): comm \"kunit_try_catch \", pid 1071, santiam\u00e9n 4294670595 (edad 732,843 s) volcado hexadecimal (primeros 32 bytes): 00 00 00 00 00 00 00 00 06 00 00 00 6b 6b 6b 6b ............kkkk a0 cc 9c 07 81 88 ff ff 78 a1 76 07 81 88 ff ff ........xv.... rastreo: [] kmalloc_trace+0x27/0xa0 [] damon_new_target+0x3f/0x1b0 [] damon_do_test_apply_tres_regiones.constprop.0+0x95/0x3e0 [] damon_test_apply_tres_regiones2+0x21e/0x260 [] kunit_generic_run_threadfn_adapter+0x4 a/0x90 [] kthread+0x2b6/0x380 [] ret_from_fork +0x2d/0x70 [] ret_from_fork_asm+0x11/0x20 objeto sin referencia 0xffff8881079ccc80 (tama\u00f1o 56): comm \"kunit_try_catch\", pid 1071, jiffies 4294670595 (edad 732.843 s) volcado hexadecimal (primero 32 bytes): 05 00 00 00 00 00 00 00 14 00 00 00 00 00 00 00 ................ 6b 6b 6b 6b 6b 6b 6b 6b 00 00 00 00 6b 6b 6b 6b kkkkkkkk....kkkk retroceso : [] damon_new_region+0x22/0x1c0 [] damon_do_test_apply_tres_regiones.constprop.0+0xd1/0x3e0 [] damon_test_apply_tres_regiones2+0x21e/0x260 [] kunit_generic_run_threadfn_adapter+0x4a/0x90 [] kthread+0x2b6/0x380 [] ret_from_fork+0x2d/0x70 ["}], "id": "CVE-2023-52560", "lastModified": "2024-12-11T15:24:15.463", "metrics": {"cvssMetricV31": [{"cvssData": {"attackComplexity": "LOW", "attackVector": "LOCAL", "availabilityImpact": "HIGH", "baseScore": 5.5, "baseSeverity": "MEDIUM", "confidentialityImpact": "NONE", "integrityImpact": "NONE", "privilegesRequired": "LOW", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H", "version": "3.1"}, "exploitabilityScore": 1.8, "impactScore": 3.6, "source": "nvd@nist.gov", "type": "Primary"}]}, "published": "2024-03-02T22:15:48.750", "references": [{"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/45120b15743fa7c0aa53d5db6dfb4c8f87be4abd"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/6b522001693aa113d97a985abc5f6932972e8e86"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/9a4fe81a8644b717d57d81ce5849e16583b13fe8"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/45120b15743fa7c0aa53d5db6dfb4c8f87be4abd"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/6b522001693aa113d97a985abc5f6932972e8e86"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/9a4fe81a8644b717d57d81ce5849e16583b13fe8"}], "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "vulnStatus": "Analyzed", "weaknesses": [{"description": [{"lang": "en", "value": "CWE-401"}], "source": "nvd@nist.gov", "type": "Primary"}]}
