{"id":"CVE-2023-53555","summary":"mm/damon/core: initialize damo_filter-\u003elist from damos_new_filter()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmm/damon/core: initialize damo_filter-\u003elist from damos_new_filter()\n\ndamos_new_filter() is not initializing the list field of newly allocated\nfilter object.  However, DAMON sysfs interface and DAMON_RECLAIM are not\ninitializing it after calling damos_new_filter().  As a result, accessing\nuninitialized memory is possible.  Actually, adding multiple DAMOS filters\nvia DAMON sysfs interface caused NULL pointer dereferencing.  Initialize\nthe field just after the allocation from damos_new_filter().","modified":"2026-04-02T09:44:26.742382Z","published":"2025-10-04T15:17:00.514Z","related":["SUSE-SU-2025:21040-1","SUSE-SU-2025:21052-1","SUSE-SU-2025:21056-1","SUSE-SU-2025:21064-1","SUSE-SU-2025:4057-1","SUSE-SU-2025:4128-1","SUSE-SU-2025:4132-1","SUSE-SU-2025:4140-1","SUSE-SU-2025:4141-1","SUSE-SU-2025:4301-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53555.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/5f1fc67f2cb8d3035d3acd273b48b97835af8afd"},{"type":"WEB","url":"https://git.kernel.org/stable/c/da7beebb49c643cd03c54447ed66595936a7a1ce"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53555.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-53555"},{"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":"98def236f63c66629fb6b2d4b69cecffc5b46539"},{"fixed":"da7beebb49c643cd03c54447ed66595936a7a1ce"},{"fixed":"5f1fc67f2cb8d3035d3acd273b48b97835af8afd"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-53555.json"}}],"schema_version":"1.7.5"}
