{"id":"CVE-2025-38080","summary":"drm/amd/display: Increase block_sequence array size","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amd/display: Increase block_sequence array size\n\n[Why]\nIt's possible to generate more than 50 steps in hwss_build_fast_sequence,\nfor example with a 6-pipe asic where all pipes are in one MPC chain. This\noverflows the block_sequence buffer and corrupts block_sequence_steps,\ncausing a crash.\n\n[How]\nExpand block_sequence to 100 items. A naive upper bound on the possible\nnumber of steps for a 6-pipe asic, ignoring the potential for steps to be\nmutually exclusive, is 91 with current code, therefore 100 is sufficient.","modified":"2026-04-02T12:47:46.738254Z","published":"2025-06-18T09:33:53.920Z","related":["SUSE-SU-2025:02249-1","SUSE-SU-2025:02254-1","SUSE-SU-2025:02307-1","SUSE-SU-2025:02333-1","SUSE-SU-2025:02335-1","SUSE-SU-2025:02538-1","SUSE-SU-2025:02923-1","SUSE-SU-2025:20475-1","SUSE-SU-2025:20483-1","SUSE-SU-2025:20493-1","SUSE-SU-2025:20498-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/38xxx/CVE-2025-38080.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/3a7810c212bcf2f722671dadf4b23ff70a7d23ee"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bf1666072e7482317cf2302621766482a21a62c7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/de67e80ab48f1f23663831007a2fa3c1471a7757"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e55c5704b12eeea27e212bfab8f7e51ad3e8ac1f"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/38xxx/CVE-2025-38080.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-38080"},{"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":"4562236b3bc0a28aeb6ee93b2d8a849a4c4e1c7c"},{"fixed":"de67e80ab48f1f23663831007a2fa3c1471a7757"},{"fixed":"e55c5704b12eeea27e212bfab8f7e51ad3e8ac1f"},{"fixed":"bf1666072e7482317cf2302621766482a21a62c7"},{"fixed":"3a7810c212bcf2f722671dadf4b23ff70a7d23ee"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-38080.json"}}],"schema_version":"1.7.5"}
