Affected files ============== The file(s) affected by this issue are: drivers/net/can/usb/peak_usb/pcan_usb_core.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/572c656802781cc57f4a3231eefa83547e75ed78 https://git.kernel.org/stable/c/61b1dd4c614935169d12bdecc26906e37b508618 https://git.kernel.org/stable/c/48822a59ecc47d353400d38b1941d3ae7591ffff https://git.kernel.org/stable/c/176c81cbf9c4e348610a421aad800087c0401f60 https://git.kernel.org/stable/c/17edec1830e48c0becd61642d0e40bc753243b16 https://git.kernel.org/stable/c/eb79ed970670344380e77d62f8188e8015648d94 https://git.kernel.org/stable/c/394c58017e5f41043584c345106cae16a4613710 https://git.kernel.org/stable/c/c443be70aaee42c2d1d251e0329e0a69dd96ae54
