The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:0563 advisory.
hw: Intel: Gather Data Sampling (GDS) side channel vulnerability (CVE-2022-40982)
kernel: use-after-free in smb2_is_status_io_timeout() (CVE-2023-1192)
kernel: UAF during login when accessing the shost ipaddress (CVE-2023-2162)
kernel: bpf: Incorrect verifier pruning leads to unsafe code paths being incorrectly marked as safe (CVE-2023-2163)
kernel: tun: bugs for oversize packet when napi frags enabled in tun_napi_alloc_frags (CVE-2023-3812)
kernel: use after free in unix_stream_sendpage (CVE-2023-4622)
kernel: net/sched: sch_hfsc UAF (CVE-2023-4623)
kernel: use-after-free in sch_qfq network scheduler (CVE-2023-4921)
kernel: fbcon: out-of-sync arrays in fbcon_mode_deleted due to wrong con2fb_map assignment (CVE-2023-38409)
kernel: netfilter: potential slab-out-of-bound access due to integer underflow (CVE-2023-42753)
kernel: IGB driver inadequate buffer size for frames larger than MTU (CVE-2023-45871)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
