{"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":"2026-05-15T11:54:44.653214951Z","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":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/44xxx/CVE-2024-44971.json","cna_assigner":"Linux"},"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":[{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.10.0"},{"fixed":"5.10.224"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.165"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.105"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.46"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.10.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2024-44971.json"}}],"schema_version":"1.7.5"}
