Category:	Mageia Linux Local Security Checks
Title:	Mageia: Security Advisory (MGASA-2023-0242)
Summary:	The remote host is missing an update for the 'kernel, kmod-virtualbox, kmod-xtables-addons' package(s) announced via the MGASA-2023-0242 advisory.
Description:	Summary: The remote host is missing an update for the 'kernel, kmod-virtualbox, kmod-xtables-addons' package(s) announced via the MGASA-2023-0242 advisory. Vulnerability Insight: This kernel update is based on upstream 5.15.122 and fixes at least the following security issue: Under specific microarchitectural circumstances, a register in 'Zen 2' CPUs may not be written to 0 correctly. This may cause data from another process and/or thread to be stored in the YMM register, which may allow an attacker to potentially access sensitive information (CVE-2023-20593, also known as Zenbleed) This update adds a kernel-side mitigation for this issue to protect users until Amd gets their fixed microcode / AGESA updates out for all affected CPUs. The fixed microcode for Amd EPYC gen2 is available in the microcode-0.20230613-2.mga8.nonfree package. For other affected CPUs, see the referenced amd.com url that has info about estimated microcode update timelines for various CPUs. For other upstream fixes in this update, see the referenced changelogs. Affected Software/OS: 'kernel, kmod-virtualbox, kmod-xtables-addons' package(s) on Mageia 8. Solution: Please install the updated package(s). CVSS Score: 4.6 CVSS Vector: AV:L/AC:L/Au:S/C:C/I:N/A:N
