|

|
||||
`2.34-60.el9_2.security.0.2` included mitigations sufficient to avoid security exposure of [CVE-2023-4911](../issues/CVE-2023-4911.md) and a backport of upstream glibc fix of [CVE-2023-4527](https://www.openwall.com/lists/oss-security/2023/09/25/1) that was not yet in upstream EL. In the update to `2.34-60.7.el9_2.security.0.3` and beyond, we retained the mitigations while rebasing on upstream EL's package with upstream fixes for these vulnerabilities (and more).

### Usage in Rocky Linux
|
||||
|

Due to EL's kABI stability and the `weak-modules` mechanism, which this package uses, the same binary package of LKRG usually works across different kernel revisions/builds within the same EL minor release (e.g., 9.4). Once there's a new minor release (e.g., 9.4 is upgraded to 9.5), we'll provide a new build of LKRG accordingly.

### Testing and recovery
|
||||
|
||||
Although the current package passed our own testing (on 9.4 and 8.10), we recommend that you only enable LKRG to start on system bootup after you've tested it for a while to ensure its compatibility with your system. If you nevertheless run into a boot time issue with LKRG later, you can disable it with the `nolkrg` kernel command-line option.
