{"id":"CVE-2026-72332","summary":"accel/amdxdna: Prevent PM resume deadlock in hwctx_sync_debug_bo()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\naccel/amdxdna: Prevent PM resume deadlock in hwctx_sync_debug_bo()\n\namdxdna_hwctx_sync_debug_bo() invokes the hardware hwctx_sync_debug_bo()\ncallback while holding xdna-\u003edev_lock.\n\nThe callback may call amdxdna_cmd_submit(), which in turn calls\namdxdna_pm_resume_get(). If the device is suspended,\namdxdna_pm_resume_get() may synchronously execute amdxdna_pm_resume(),\nwhich also acquires xdna-\u003edev_lock, resulting in a deadlock.\n\nAvoid the deadlock by calling amdxdna_pm_resume_get() before holding\nxdna-\u003edev_lock in both amdxdna_hwctx_sync_debug_bo() and\namdxdna_drm_config_hwctx_ioctl()","modified":"2026-08-18T03:31:27.568469595Z","published":"2026-08-15T05:55:41.878Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72332.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/2d8eeb0578ae3aadf112fd3e1997e58178f75979"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e35c9cf5512814fb04f369f2eada64f0a7164609"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72332.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72332"},{"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":"7ea0468380216c10b73633b976d33efa8c12d375"},{"fixed":"2d8eeb0578ae3aadf112fd3e1997e58178f75979"},{"fixed":"e35c9cf5512814fb04f369f2eada64f0a7164609"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72332.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72332.json"}}],"schema_version":"1.9.0"}
