Affected files ============== The file(s) affected by this issue are: sound/usb/stream.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/7e2c1b0f6dd9abde9e60f0f9730026714468770f https://git.kernel.org/stable/c/6d5dc96b154be371df0d62ecb07efe400701ed8a https://git.kernel.org/stable/c/5cd466673b34bac369334f66cbe14bb77b7d7827 https://git.kernel.org/stable/c/9af1658ba293458ca6a13f70637b9654fa4be064 https://git.kernel.org/stable/c/629af0d5fe94a35f498ba2c3f19bd78bfa591be6 https://git.kernel.org/stable/c/22cad1b841a63635a38273b799b4791f202ade72 https://git.kernel.org/stable/c/c8a24fd281dcdf3c926413dafbafcf35cde517a9 https://git.kernel.org/stable/c/6d88b289fb0a8d055cb79d1c46a56aba7809d96d https://git.kernel.org/stable/c/a39d51ff1f52cd0b6fe7d379ac93bd8b4237d1b7
