This register indicates which crypto algorithms are implemented in silicon. Supported algorithms are registered on this basis. Unregister algorithms on the same basis. Currently, all algorithms are unregistered, even those not supported by HW. This results in panic on platforms that don't have all options implemented in silicon. The Linux kernel CVE team has assigned CVE-2026-45854 to this issue. Affected and fixed versions =========================== Issue introduced in 6.15 with commit 9739f5f93b7806a684713ba42e6ed2d1df7c8100 and fixed in 6.18.14 with commit 243d642ff5809811208fa1707b7ab8a6ab4b1d68 Issue introduced in 6.15 with commit 9739f5f93b7806a684713ba42e6ed2d1df7c8100 and fixed in 6.19.4 with commit 4c1c5a1d720fdacea060e106c7dd79417243d121 Issue introduced in 6.15 with commit 9739f5f93b7806a684713ba42e6ed2d1df7c8100 and fixed in 7.0 with commit 0ceeadc7b53a041d89d5843f6bf0ccb7c98b0b4f Please see https://www.kernel.org for a full list of currently supported kernel versions by the kernel community. 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-2026-45854 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/inside-secure/eip93/eip93-main.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/243d642ff5809811208fa1707b7ab8a6ab4b1d68 https://git.kernel.org/stable/c/4c1c5a1d720fdacea060e106c7dd79417243d121 https://git.kernel.org/stable/c/0ceeadc7b53a041d89d5843f6bf0ccb7c98b0b4f
