Normally this is ok, but for some request types, bits other than bit 8 could be set and the check for the endpoint length could not stall correctly. Fix that up by only checking the single bit. The Linux kernel CVE team has assigned TESTING_NOT_REAL_ID_YET to this issue. Affected versions ================= Issue introduced in 4.4.295 and fixed in 4.4.296 Issue introduced in 4.9.293 and fixed in 4.9.294 Issue introduced in 4.14.258 and fixed in 4.14.259 Issue introduced in 4.19.221 and fixed in 4.19.222 Issue introduced in 5.4.165 and fixed in 5.4.168 Issue introduced in 5.10.85 and fixed in 5.10.88 Issue introduced in 5.15.8 and fixed in 5.15.11 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 change to resolve this issue can be found at: https://git.kernel.org/stable/linux/c/f08adf5add9a071160c68bb2a61d697f39ab0758
