Description

In the Linux kernel, the following vulnerability has been resolved: mmc: sdhci-pci: Fix possible memory leak caused by missing pci_dev_put() pci_get_device() will increase the reference count for the returned pci_dev. We need to use pci_dev_put() to decrease the reference count before amd_probe() returns. There is no problem for the 'smbus_dev == NULL' branch because pci_dev_put() can also handle the NULL input parameter case.

Affected configurations

• linux linux kernel (>= 4.4 < 4.14.300) • linux linux kernel (>= 4.15 < 4.19.267) • linux linux kernel (>= 4.20 < 5.4.225) • linux linux kernel (>= 5.5 < 5.10.156) • linux linux kernel (>= 5.11 < 5.15.80) • linux linux kernel (>= 5.16 < 6.0.10) • linux linux kernel 6.1
