Affected files ============== The file(s) affected by this issue are: drivers/media/usb/dvb-usb/m920x.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/809623fedc31f4e74039d93bb75a8993635d7534 https://git.kernel.org/stable/c/c0178e938f110cdf6937f26975c0c951dbb1d9db https://git.kernel.org/stable/c/75d6ef197c488cd852493b4a419274e3489da79d https://git.kernel.org/stable/c/d13a84874a2e0236c9325b3adc8e126d0888ad6b https://git.kernel.org/stable/c/7ca7cd02114ac8caa6b0a64734b9af6be1559353 https://git.kernel.org/stable/c/2b6e20ef0585a467c24c7e4fde28518e5b33225a https://git.kernel.org/stable/c/4feed3dfca722c6d74865a37cab853c58e6aa190 https://git.kernel.org/stable/c/2cc9f11aeae2887a4db25c27323fc445f4b49e86 https://git.kernel.org/stable/c/ea9ef6c2e001c5dc94bee35ebd1c8a98621cf7b8
