The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:1278 advisory.
This is a kernel live patch module which is automatically loaded by the RPM post-install script to modify the code of a running kernel.
Security Fix(es):
* kernel: ktls overwrites readonly memory pages when using function splice with a ktls socket as destination (CVE-2024-0646)
* kernel: use-after-free in sch_qfq network scheduler (CVE-2023-4921)
* kernel: IGB driver inadequate buffer size for frames larger than MTU (CVE-2023-45871)
* kernel: use after free in nvmet_tcp_free_crypto in NVMe (CVE-2023-5178)
* kernel: net/sched: sch_hfsc UAF (CVE-2023-4623)
* kernel: net/sched: sch_qfq component can be exploited if in qfq_change_agg function happens qfq_enqueue overhead (CVE-2023-3611)
* kernel: nf_tables: stack-out-of-bounds-read in nft_byteorder_eval() (CVE-2023-35001)
* kernel: UAF in nftables when nft_set_lookup_global triggered after handling named and anonymous sets in batch requests (CVE-2023-3390)
* kernel: out-of-bounds write in qfq_change_class function (CVE-2023-31436)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
