Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> perf/x86/intel/uncore: Fix reference count leak in hswep_has_limit_sbox()<br /> <br /> pci_get_device() will increase the reference count for the returned<br /> &amp;#39;dev&amp;#39;. We need to call pci_dev_put() to decrease the reference count.<br /> Since &amp;#39;dev&amp;#39; is only used in pci_read_config_dword(), let&amp;#39;s add<br /> pci_dev_put() right after it.
