Unaffected versions might change over time as fixes are backported to older supported kernel versions. The official CVE entry at https://cve.org/CVERecord/?id=CVE-2022-49106 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/staging/vc04_services/interface/vchiq_arm/vchiq_arm.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/176df12b38c70b0a45e6392a0ee5bc83489dfc29 https://git.kernel.org/stable/c/4627250cabaa80278d3ab01ad107893cea83799f https://git.kernel.org/stable/c/51e5e5c34c22c0bfec0808d8c33e0b2fcf4c7c89 https://git.kernel.org/stable/c/aa899e686d442c63d50f4d369cc02dbbf0941cb0
