Affected files ============== The file(s) affected by this issue are: drivers/usb/dwc3/dwc3-qcom.c 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: https://git.kernel.org/stable/c/648a163cff21ea355c8765e882ba8bf66a870a3e https://git.kernel.org/stable/c/74f8606ddfa450d2255b4e61472a7632def1e8c4 https://git.kernel.org/stable/c/b626cd5e4a87a281629e0c2b07519990077c0fbe https://git.kernel.org/stable/c/c3b322b84ab5dda7eaca9ded763628b7467734f4 https://git.kernel.org/stable/c/134a7d4642f11daed6bbc378f930a54dd0322291 https://git.kernel.org/stable/c/097fb3ee710d4de83b8d4f5589e8ee13e0f0541e
