{"id":"CVE-2026-43146","summary":"media: iris: Add buffer to list only after successful allocation","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: iris: Add buffer to list only after successful allocation\n\nMove `list_add_tail()` to after `dma_alloc_attrs()` succeeds when creating\ninternal buffers. Previously, the buffer was enqueued in `buffers-\u003elist`\nbefore the DMA allocation. If the allocation failed, the function returned\n`-ENOMEM` while leaving a partially initialized buffer in the list, which\ncould lead to inconsistent state and potential leaks.\n\nBy adding the buffer to the list only after `dma_alloc_attrs()` succeeds,\nwe ensure the list contains only valid, fully initialized buffers.","modified":"2026-07-08T08:09:34.249004961Z","published":"2026-05-06T11:27:29.562Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43146.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/2d0bbd982dfdd67da488a772f7a8a1bdca7642bf"},{"type":"WEB","url":"https://git.kernel.org/stable/c/45b30f65feeb4d5570d5337793bb0f298be813d2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/98b4c4c90f1e11caecbe2093dbe3a901d338bc81"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43146.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43146"},{"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":"73702f45db81b74897b2808aaa13484826156006"},{"fixed":"45b30f65feeb4d5570d5337793bb0f298be813d2"},{"fixed":"98b4c4c90f1e11caecbe2093dbe3a901d338bc81"},{"fixed":"2d0bbd982dfdd67da488a772f7a8a1bdca7642bf"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-43146.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.15.0"},{"fixed":"6.18.16"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"6.19.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-43146.json"}}],"schema_version":"1.7.5"}
