{"id":"CVE-2024-53109","summary":"nommu: pass NULL argument to vma_iter_prealloc()","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":"2026-04-16T04:32:35.646137605Z","published":"2024-12-02T13:44:41.622Z","related":["USN-7276-1","USN-7277-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/53xxx/CVE-2024-53109.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/247d720b2c5d22f7281437fd6054a138256986ba"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8bbf0ab631cdf1dade6745f137cff98751e6ced7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/aceaf33b7666b72dfb86e0aa977be81e3bcbc727"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/53xxx/CVE-2024-53109.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-53109"},{"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":"b5df09226450165c434084d346fcb6d4858b0d52"},{"fixed":"8bbf0ab631cdf1dade6745f137cff98751e6ced7"},{"fixed":"aceaf33b7666b72dfb86e0aa977be81e3bcbc727"},{"fixed":"247d720b2c5d22f7281437fd6054a138256986ba"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-53109.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"}]}
