{"id":"CVE-2026-53141","summary":"drm/v3d: Fix global performance monitor reference counting","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/v3d: Fix global performance monitor reference counting\n\nIn the SET_GLOBAL ioctl, v3d_perfmon_find() bumps the reference count on\nthe perfmon it returns, but v3d_perfmon_set_global_ioctl() and\nv3d_perfmon_delete() fail to release that reference on several paths:\n\n  1. v3d_perfmon_set_global_ioctl() leaks the reference on its error\n     paths.\n\n  2. CLEAR_GLOBAL leaks both the find reference and the reference\n     previously stashed in v3d-\u003eglobal_perfmon by the SET_GLOBAL ioctl\n     that configured it.\n\n  3. Destroying a perfmon that is the current global perfmon leaks the\n     reference stashed by the SET_GLOBAL ioctl.\n\nRelease each of these references explicitly.","modified":"2026-07-17T21:07:32.875969652Z","published":"2026-06-25T08:38:29.283Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53141.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/3e1947573140a57119294f0bff39ee18d93f23e1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6bf7e2affc6e62da7add393d7f352d4040f5bc27"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ed2eaf3b7b1820b690e4b896d344e00027526a25"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53141.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53141"},{"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":"c6eabbab359c156669e10d5dec3e71e80ff09bd2"},{"fixed":"3e1947573140a57119294f0bff39ee18d93f23e1"},{"fixed":"ed2eaf3b7b1820b690e4b896d344e00027526a25"},{"fixed":"6bf7e2affc6e62da7add393d7f352d4040f5bc27"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-53141.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.14.0"},{"fixed":"6.18.36"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.13"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-53141.json"}}],"schema_version":"1.7.5"}
