{"id":"CVE-2026-93139","summary":"drm/amdgpu/mes: Fix hung_queue_db_array loop limit for multi-XCC","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amdgpu/mes: Fix hung_queue_db_array loop limit for multi-XCC\n\nThe loop iterated only AMDGPU_MAX_MES_PIPES times, leaving entries\nuninitialized for multi-XCC GPUs. This causes null pointer dereferences\nwhen accessing arrays indexed by XCC ID \u003e= 2. Extend the loop to cover\nall XCCs (AMDGPU_MAX_MES_PIPES * num_xcc), matching other per-XCC\narrays.","modified":"2026-09-19T03:47:27.848262521Z","published":"2026-09-17T16:11:39.448Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93139.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/2c256086a363f01f9840a57949506eccf5c990a6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7ff668cfc3960ed5b944ac35129f18a15ea08b74"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93139.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-93139"},{"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":"a132fc9bc2f8b394a2f75947a0e1f5c22482a94c"},{"fixed":"7ff668cfc3960ed5b944ac35129f18a15ea08b74"},{"fixed":"2c256086a363f01f9840a57949506eccf5c990a6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-93139.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.2.0"},{"fixed":"7.2.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-93139.json"}}],"schema_version":"1.9.0"}
