The\nmpc_combine is an array that records all the planes per asic. Therefore\nMAX_PLANES should be used as the array size. Using MAX_SURFACES causes\narray overflow when there are more than 3 planes.\n\n[how]\nUse the MAX_PLANES for the mpc_combine array size.","affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"4562236b3bc0a28aeb6ee93b2d8a849a4c4e1c7c"},{"fixed":"0bd8ef618a42d7e6ea3f701065264e15678025e3"},{"fixed":"39079fe8e660851abbafa90cd55cbf029210661f"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-26914.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.15.0"},{"fixed":"6.7.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-26914.json"}}],"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0bd8ef618a42d7e6ea3f701065264e15678025e3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/39079fe8e660851abbafa90cd55cbf029210661f"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/26xxx/CVE-2024-26914.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-26914"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/26xxx/CVE-2024-26914.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
