{"id":"AZL-48653","summary":"CVE-2024-44971 affecting package kernel for versions less than 5.15.167.1-1","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":"2026-04-21T04:33:04.387402Z","published":"2024-09-04T19:15:31Z","upstream":["CVE-2024-44971"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-44971"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.15.167.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-48653.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
