Description OSIDB Bzimport 2025-09-15 15:02:20 UTC 
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.
