{"id":"CVE-2026-98179","summary":"drm/amdgpu: fix rmmio iounmap skipped on device removal","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amdgpu: fix rmmio iounmap skipped on device removal\n\namdgpu_pci_remove() calls drm_dev_unplug() before fini_sw(), so\ndrm_dev_enter() is already false there and the iounmap() guarded by it\nis skipped. This .remove path runs on both hot-unplug and plain rmmod,\nso the register BAR ioremap mapping leaks one instance per unload.\n\nUnmap rmmio unconditionally (guard only on non-NULL) and drop the now\nunused idx.\n\n(cherry picked from commit dd6f86a97260e5207d3329ad03aa89fdad61b1e6)","modified":"2026-10-08T02:52:52.607332654Z","published":"2026-10-06T08:44:22.410Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98179.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/5155002b03b24ba3ef91c5c313b8cf0171b24904"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a645584c3ccc493ee835f77155829442bd7578c3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cd55dde2b63789a3dafe982c89844f537501d096"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e81502d6791df9ecd003bfb2ca44f0d1f1b38439"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98179.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98179"},{"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":"62d5f9f7110ad374db67ab4820f4ff2d916c3cdb"},{"fixed":"e81502d6791df9ecd003bfb2ca44f0d1f1b38439"},{"fixed":"cd55dde2b63789a3dafe982c89844f537501d096"},{"fixed":"a645584c3ccc493ee835f77155829442bd7578c3"},{"fixed":"5155002b03b24ba3ef91c5c313b8cf0171b24904"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98179.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.17.0"},{"fixed":"6.12.112"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.54"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.8"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98179.json"}}],"schema_version":"1.9.0"}
