{"id":"CVE-2024-44971","summary":"net: dsa: bcm_sf2: Fix a possible memory leak in bcm_sf2_mdio_register()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: dsa: bcm_sf2: Fix a possible memory leak in bcm_sf2_mdio_register()\n\nbcm_sf2_mdio_register() calls of_phy_find_device() and then\nphy_device_remove() in a loop to remove existing PHY devices.\nof_phy_find_device() eventually calls bus_find_device(), which calls\nget_device() on the returned struct device * to increment the refcount.\nThe current implementation does not decrement the refcount, which causes\nmemory leak.\n\nThis commit adds the missing phy_device_free() call to decrement the\nrefcount via put_device() to balance the refcount.","modified":"2026-04-16T04:31:24.919046687Z","published":"2024-09-04T18:56:47.475Z","related":["SUSE-SU-2024:3551-1","SUSE-SU-2024:3553-1","SUSE-SU-2024:3561-1","SUSE-SU-2024:3564-1","SUSE-SU-2024:3569-1","SUSE-SU-2024:3587-1","SUSE-SU-2024:3592-1","SUSE-SU-2025:20073-1","SUSE-SU-2025:20077-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/44xxx/CVE-2024-44971.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/7feef10768ea71d468d9bbc1e0d14c461876768c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a7d2808d67570e6acae45c2a96e0d59986888e4c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b7b8d9f5e679af60c94251fd6728dde34be69a71"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c05516c072903f6fb9134b8e7e1ad4bffcdc4819"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e3862093ee93fcfbdadcb7957f5f8974fffa806a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f3d5efe18a11f94150fee8b3fda9d62079af640a"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/10/msg00003.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/44xxx/CVE-2024-44971.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-44971"},{"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":"771089c2a485958e423f305e974303760167b45c"},{"fixed":"b7b8d9f5e679af60c94251fd6728dde34be69a71"},{"fixed":"c05516c072903f6fb9134b8e7e1ad4bffcdc4819"},{"fixed":"7feef10768ea71d468d9bbc1e0d14c461876768c"},{"fixed":"a7d2808d67570e6acae45c2a96e0d59986888e4c"},{"fixed":"f3d5efe18a11f94150fee8b3fda9d62079af640a"},{"fixed":"e3862093ee93fcfbdadcb7957f5f8974fffa806a"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-44971.json"}}],"schema_version":"1.7.5"}
