{"id":"CVE-2022-50615","summary":"perf/x86/intel/uncore: Fix reference count leak in snr_uncore_mmio_map()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nperf/x86/intel/uncore: Fix reference count leak in snr_uncore_mmio_map()\n\npci_get_device() will increase the reference count for the returned\npci_dev, so snr_uncore_get_mc_dev() will return a pci_dev with its\nreference count increased. We need to call pci_dev_put() to decrease the\nreference count. Let's add the missing pci_dev_put().","modified":"2026-03-20T12:22:36.287707Z","published":"2025-12-08T01:16:28.314Z","related":["SUSE-SU-2026:0263-1","SUSE-SU-2026:0316-1","SUSE-SU-2026:0317-1","SUSE-SU-2026:0411-1","SUSE-SU-2026:0617-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/50xxx/CVE-2022-50615.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/433bd587dca5c3f7157fef2fe571290cd392cbf6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8ebd16c11c346751b3944d708e6c181ed4746c39"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a67146437b6428069b71a7e5e740a2a8e1c40ac9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d2afced51108813256d8072c6e464b0c9f0bb890"},{"type":"WEB","url":"https://git.kernel.org/stable/c/dc7f07bc1ebb56a23fd1c4f664db5cbeb8900800"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/50xxx/CVE-2022-50615.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-50615"},{"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":"ee49532b38dd084650bf715eabe7e3828fb8d275"},{"fixed":"d2afced51108813256d8072c6e464b0c9f0bb890"},{"fixed":"433bd587dca5c3f7157fef2fe571290cd392cbf6"},{"fixed":"a67146437b6428069b71a7e5e740a2a8e1c40ac9"},{"fixed":"dc7f07bc1ebb56a23fd1c4f664db5cbeb8900800"},{"fixed":"8ebd16c11c346751b3944d708e6c181ed4746c39"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2022-50615.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.3.0"},{"fixed":"5.10.163"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.86"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.0.16"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.1.0"},{"fixed":"6.1.2"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2022-50615.json"}}],"schema_version":"1.7.5"}
