{"id":"CVE-2026-72146","summary":"dmaengine: sh: rz-dmac: Move interrupt request after everything is set up","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndmaengine: sh: rz-dmac: Move interrupt request after everything is set up\n\nOnce the interrupt is requested, the interrupt handler may run immediately.\nSince the IRQ handler can access channel-\u003ech_base, which is initialized\nonly after requesting the IRQ, this may lead to invalid memory access.\nLikewise, the IRQ thread may access uninitialized data (the ld_free,\nld_queue, and ld_active lists), which may also lead to issues.\n\nRequest the interrupts only after everything is set up. To keep the error\npath simpler, use dmam_alloc_coherent() instead of dma_alloc_coherent().","modified":"2026-08-21T03:30:25.547242715Z","published":"2026-08-15T05:53:18.431Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72146.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/07ae600bd353b22f31a8f1007269744fafc7f123"},{"type":"WEB","url":"https://git.kernel.org/stable/c/0e0c5b3cf374ebf3c589741751e1fbc67f53ec2f"},{"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/d24d53323e817d79a4bd111bd10b34dbc96e64a8"},{"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"5000d37042a61ca556fde2782ca40dbfa802ea16"},{"fixed":"d24d53323e817d79a4bd111bd10b34dbc96e64a8"},{"fixed":"0e0c5b3cf374ebf3c589741751e1fbc67f53ec2f"},{"fixed":"5b12de6229d662864ee22c11d4876652b40120f0"},{"fixed":"2a4d9e2234c3f817bb0ddbc8680d09ce9be84f93"},{"fixed":"ec9f66c91bffdb69d309bae6dfb387562db7ebc8"},{"fixed":"07ae600bd353b22f31a8f1007269744fafc7f123"},{"fixed":"731712403ddb39d1a76a11abf339a0615bc85de7"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72146.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.15.0"},{"fixed":"5.15.216"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.183"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.148"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.101"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.42"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72146.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
