| Subject: CVE-2022-49868: phy: ralink: mt7621-pci: add sentinel to quirks table |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| phy: ralink: mt7621-pci: add sentinel to quirks table |
| |
| With mt7621 soc_dev_attr fixed to register the soc as a device, |
| kernel will experience an oops in soc_device_match_attr |
| |
| This quirk test was introduced in the staging driver in |
| commit 9445ccb3714c ("staging: mt7621-pci-phy: add quirks for 'E2' |
| revision using 'soc_device_attribute'"). 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 |
| |
| The Linux kernel CVE team has assigned CVE-2022-49868 to this issue. |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
