In the Linux kernel, the following vulnerability has been resolved:
phy: ralink: mt7621-pci: add sentinel to quirks table
With mt7621 socdevattr fixed to register the soc as a device, kernel will experience an oops in socdevicematch_attr
This quirk test was introduced in the staging driver in commit 9445ccb3714c ("staging: mt7621-pci-phy: add quirks for 'E2' revision using 'socdeviceattribute'"). The staging driver was removed, and later re-added in commit d87da32372a0 ("phy: ralink: Add PHY driver for MT7621 PCIe PHY") for kernel 5.11
