Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
PCI: Fix pci_slot_trylock() error handling<br />
<br />
Commit a4e772898f8b ("PCI: Add missing bridge lock to pci_bus_lock()")<br />
delegates the bridge device&#39;s pci_dev_trylock() to pci_bus_trylock() in<br />
pci_slot_trylock(), but it forgets to remove the corresponding<br />
pci_dev_unlock() when pci_bus_trylock() fails.<br />
<br />
Before a4e772898f8b, the code did:<br />
<br />
if (!pci_dev_trylock(dev)) /* subordinate) {<br />
if (!pci_bus_trylock(dev->subordinate)) {<br />
pci_dev_unlock(dev); /*
