Category:	Mageia Linux Local Security Checks
Title:	Mageia: Security Advisory (MGASA-2021-0398)
Summary:	The remote host is missing an update for the 'kernel-linus' package(s) announced via the MGASA-2021-0398 advisory.
Description:	Summary: The remote host is missing an update for the 'kernel-linus' package(s) announced via the MGASA-2021-0398 advisory. Vulnerability Insight: This kernel-linus update is based on upstream 5.10.56 and fixes at least the following security issues: In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from kernel memory via a Speculative Store Bypass side-channel attack because the protection mechanism neglects the possibility of uninitialized memory locations on the BPF stack (CVE-2021-34556). In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from kernel memory via a Speculative Store Bypass side-channel attack because a certain preempting store operation does not necessarily occur before a store operation that has an attacker-controlled value (CVE-2021-35477). For other upstream fixes, see the referenced changelogs. Affected Software/OS: 'kernel-linus' package(s) on Mageia 8. Solution: Please install the updated package(s). CVSS Score: 2.1 CVSS Vector: AV:L/AC:L/Au:N/C:P/I:N/A:N
