To keep the error\npath simpler, use dmam_alloc_coherent() instead of dma_alloc_coherent().","published":"2026-08-15T05:53:18.431Z","modified":"2026-08-16T03:48:32.694803433Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Linux","name":"Kernel","fixedVersion":"6.6.148"}],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/07ae600bd353b22f31a8f1007269744fafc7f123"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2a4d9e2234c3f817bb0ddbc8680d09ce9be84f93"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5b12de6229d662864ee22c11d4876652b40120f0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/731712403ddb39d1a76a11abf339a0615bc85de7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ec9f66c91bffdb69d309bae6dfb387562db7ebc8"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72146.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72146"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-16T03:48:32.694803433Z"}}
