    Summary: Updated kernel-linus packages fix security vulnerabilities

    Details: This kernel-linus update is based on upstream 5.15.43 and fixes at least the following security issues: A race condition in the perf subsystem allows for a local privilege escalation. NOTE: Mageia kernels by default has disabled the perf usage for unprivileged users, effectively rendering this vulnerability harmless (CVE-2022-1729). Kernel could allow a remote attacker to bypass security restrictions, caused by a lockdown break issue. By sending a specially-crafted request using the kernel debugger, an attacker could exploit this vulnerability to perform read and write access to kernel memory (CVE-2022-21499). For other upstream fixes, see the referenced changelogs.
