On normal loop completion, dma_fence_unwrap_next()\nreleases this via dma_fence_chain_walk() -> dma_fence_put().\n\nWhen virtio_gpu_do_fence_wait() fails and the function returns early\nfrom inside the loop, the cursor->chain reference is never released.\nThis is the only caller in the entire kernel that does an early return\ninside dma_fence_unwrap_for_each.\n\nAdd dma_fence_put(itr.chain) before the early return.","affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"eba57fb5498f2858768321e64570caea188455b8"},{"fixed":"898bd0ccfed71651b881660c5d20ad73b5203174"},{"fixed":"73524e9f96a278b521f257a78a845c49eb522bc1"},{"fixed":"8348567a6afb24e2c9cafe8a321162d0eebe1411"},{"fixed":"c0fffc874c264292e769f26194a2a5e66ce31810"},{"fixed":"3f26bb732cc136ab20176697c92f32c9c84cb125"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53190.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.5.0"},{"fixed":"6.6.143"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.94"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.36"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.13"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53190.json"}}],"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/3f26bb732cc136ab20176697c92f32c9c84cb125"},{"type":"WEB","url":"https://git.kernel.org/stable/c/73524e9f96a278b521f257a78a845c49eb522bc1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8348567a6afb24e2c9cafe8a321162d0eebe1411"},{"type":"WEB","url":"https://git.kernel.org/stable/c/898bd0ccfed71651b881660c5d20ad73b5203174"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c0fffc874c264292e769f26194a2a5e66ce31810"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53190.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53190"},{"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/2026/53xxx/CVE-2026-53190.json"}}
