{"id":"AZL-54126","summary":"CVE-2024-53109 affecting package kernel for versions less than 6.6.64.2-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnommu: pass NULL argument to vma_iter_prealloc()\n\nWhen deleting a vma entry from a maple tree, it has to pass NULL to\nvma_iter_prealloc() in order to calculate internal state of the tree, but\nit passed a wrong argument.  As a result, nommu kernels crashed upon\naccessing a vma iterator, such as acct_collect() reading the size of vma\nentries after do_munmap().\n\nThis commit fixes this issue by passing a right argument to the\npreallocation call.","modified":"2026-04-01T05:18:11.796964Z","published":"2024-12-02T14:15:11Z","upstream":["CVE-2024-53109"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-53109"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.64.2-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-54126.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"}]}
