However, dma_chan_put() call dma_device_put() which could\nrelease the last reference of the device if the DMA provider is already\ngone and hence free it.\n\nFixes it by moving dma_chan_put() after the check.","published":"2026-08-15T05:57:16.396Z","modified":"2026-08-16T03:48:53.826317273Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Linux","name":"Kernel","fixedVersion":"5.10.261"}],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0bc191050c3253da8ef4bfaf157c44efed6e22cd"},{"type":"WEB","url":"https://git.kernel.org/stable/c/329ec20a86091d2a6e5b4fe507545e7d678a22a2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3b0240483dc977dbec4f3bc7a5383d4691ecb625"},{"type":"WEB","url":"https://git.kernel.org/stable/c/444f96066937f3fdf0e79b53289cff223c7d638b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5876f38b67a309c00628942cb25679749b53b397"},{"type":"WEB","url":"https://git.kernel.org/stable/c/92f853f0645aebf1d05d333e97ab7c342ace1892"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9bdc8dce4068dadbdf7cf5ad6d4983e2afffedce"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ab438a9efb9042c79d2f8db28a326d55feb8591f"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72476.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72476"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-16T03:48:53.826317273Z"}}
