If the number of events\nin an event_group is greater than HISI_PCIE_MAX_COUNTERS, the memory write\noverflow of event_group array occurs.\n\nAdd array index check to fix the possible array out of bounds violation,\nand return directly when write new events are written to array bounds.\n\nThere are 9 different events in an event_group.\n[1] perf stat -e '{pmu/event1/, ... ,pmu/event9/}'","modified":"2026-04-16T00:06:09.453877558Z","published":"2024-06-19T13:35:35.588Z","related":["SUSE-SU-2024:2571-1","SUSE-SU-2024:2896-1","SUSE-SU-2024:2973-1","SUSE-SU-2025:20008-1","SUSE-SU-2025:20028-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/38xxx/CVE-2024-38569.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/3d1face00ebb7996842aee4214d7d0fb0c77b1e9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/567d34626c22b36579ec0abfdf5eda2949044220"},{"type":"WEB","url":"https://git.kernel.org/stable/c/77fce82678ea5fd51442e62febec2004f79e041b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8e9aab2492178f25372f1820bfd9289fbd74efd0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ff48247144d13a3a0817127703724256008efa78"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/38xxx/CVE-2024-38569.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-38569"},{"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":"8404b0fbc7fbd42e5c5d28cdedd450e70829c77a"},{"fixed":"3d1face00ebb7996842aee4214d7d0fb0c77b1e9"},{"fixed":"8e9aab2492178f25372f1820bfd9289fbd74efd0"},{"fixed":"567d34626c22b36579ec0abfdf5eda2949044220"},{"fixed":"ff48247144d13a3a0817127703724256008efa78"},{"fixed":"77fce82678ea5fd51442e62febec2004f79e041b"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2024-38569.json"}}],"schema_version":"1.7.5"}
