The remote SUSE Linux SLES12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:3006-1 advisory.
An issue in Zen 2 CPUs, under specific microarchitectural circumstances, may allow an attacker to potentially access sensitive information. (CVE-2023-20593)
A use after free flaw was found in hfsplus_put_super in fs/hfsplus/super.c in the Linux Kernel. This flaw could allow a local user to cause a denial of service problem. (CVE-2023-2985)
Linux Kernel nftables Out-Of-Bounds Read/Write Vulnerability; nft_byteorder poorly handled vm register contents when CAP_NET_ADMIN is in any user or network namespace (CVE-2023-35001)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
