The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:7539 advisory.

  • hw: Intel: Gather Data Sampling (GDS) side channel vulnerability (CVE-2022-40982)

  • kernel: use-after-free due to race condition occurring in dvb_register_device() (CVE-2022-45884)

  • kernel: use-after-free due to race condition occurring in dvb_net.c (CVE-2022-45886)

  • kernel: use-after-free due to race condition occurring in dvb_ca_en50221.c (CVE-2022-45919)

  • kernel: use-after-free in smb2_is_status_io_timeout() (CVE-2023-1192)

  • kernel: net/sched: cls_u32 component reference counter leak if tcf_change_indev() fails (CVE-2023-3609)

  • kernel: net/sched: Use-after-free vulnerabilities in the net/sched classifiers: cls_fw, cls_u32 and cls_route (CVE-2023-4128, CVE-2023-4206, CVE-2023-4207, CVE-2023-4208)

  • kernel: Race between task migrating pages and another task calling exit_mmap to release those same pages getting invalid opcode BUG in include/linux/swapops.h (CVE-2023-4732)

  • 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: mm/slab_common: slab_caches list corruption after kmem_cache_destroy() (CVE-2023-52562)

Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
