Description

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

Affected configurations

• linux linux kernel (>= 4.19.189 < 4.19.270) • linux linux kernel (>= 5.4.115 < 5.4.229) • linux linux kernel (>= 5.10.33 < 5.10.163) • linux linux kernel (>= 5.11.17 < 5.12) • linux linux kernel (>= 5.12.1 < 5.15.86) • linux linux kernel (>= 5.16 < 6.0.16) • linux linux kernel (>= 6.1 < 6.1.2) • linux linux kernel 5.12
