Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> PCI: mt7621: Add sentinel to quirks table<br /> <br /> Current driver is missing a sentinel in the struct soc_device_attribute<br /> array, which causes an oops when assessed by the<br /> soc_device_match(mt7621_pcie_quirks_match) call.<br /> <br /> This was only exposed once the CONFIG_SOC_MT7621 mt7621 soc_dev_attr<br /> was fixed to register the SOC as a device, in:<br /> <br /> commit 7c18b64bba3b ("mips: ralink: mt7621: do not use kzalloc too early")<br /> <br /> Fix it by adding the required sentinel.
