The official CVE entry at https://cve.org/CVERecord/?id=CVE-2026-80922 will be updated if fixes are backported, please check that for the most up to date information about this issue. Affected files ============== The file(s) affected by this issue are: drivers/crypto/qcom-rng.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/813e6718a199befc4f26f54bdd899fbfa11515e5 https://git.kernel.org/stable/c/4c0018320942003bfedd0a1c4cce3f036d363a7f https://git.kernel.org/stable/c/143c74034a1c47b0a1a64e7ca7153e7739bd1244 https://git.kernel.org/stable/c/3c7101cfc52e378bcb0a46962145e39c9051dd5d https://git.kernel.org/stable/c/4ef04bdc0c9f98836d1638be516f6bf1bad55f69
