{"id":"CVE-2024-38568","summary":"drivers/perf: hisi: hns3: Fix out-of-bound access when valid event group","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrivers/perf: hisi: hns3: Fix out-of-bound access when valid event group\n\nThe perf tool allows users to create event groups through following\ncmd [1], but the driver does not check whether the array index is out\nof bounds when writing data to the event_group array. If the number of\nevents in an event_group is greater than HNS3_PMU_MAX_HW_EVENTS, the\nmemory write overflow 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":"2026-04-02T12:16:50.310472Z","published":"2024-06-19T13:35:34.925Z","related":["MGASA-2024-0263","MGASA-2024-0266","SUSE-SU-2024:2372-1","SUSE-SU-2024:2394-1","SUSE-SU-2024:2571-1","SUSE-SU-2024:2896-1","SUSE-SU-2024:2939-1","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-2024-38568.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/3669baf308308385a2ab391324abdde5682af5aa"},{"type":"WEB","url":"https://git.kernel.org/stable/c/81bdd60a3d1d3b05e6cc6674845afb1694dd3a0e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/aa2d3d678895c8eedd003f1473f87d3f06fe6ec7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b5120d322763c15c978bc47beb3b6dff45624304"},{"type":"WEB","url":"https://git.kernel.org/stable/c/be1fa711e59c874d049f592aef1d4685bdd22bdf"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/38xxx/CVE-2024-38568.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-38568"},{"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":"66637ab137b44914356a9dc7a9b3f8ebcf0b0695"},{"fixed":"3669baf308308385a2ab391324abdde5682af5aa"},{"fixed":"be1fa711e59c874d049f592aef1d4685bdd22bdf"},{"fixed":"b5120d322763c15c978bc47beb3b6dff45624304"},{"fixed":"aa2d3d678895c8eedd003f1473f87d3f06fe6ec7"},{"fixed":"81bdd60a3d1d3b05e6cc6674845afb1694dd3a0e"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-38568.json"}}],"schema_version":"1.7.5"}
