The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:6990 advisory.
The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.
Security Fix(es):
* kernel: mm/sparsemem: fix race in accessing memory_section->usage (CVE-2023-52489)
* kernel: hwmon: (mlxreg-fan) Return non-zero value when fan current state is enforced from sysfs (CVE-2021-47393)
* kernel: net/smc: Fix NULL pointer dereferencing in smc_vlan_by_tcpsk() (CVE-2021-47559)
* kernel: ACPICA: Revert ACPICA: avoid Info: mapping multiple BARs. Your kernel is fine.
(CVE-2024-40984)
* kernel: net/sched: act_api: fix possible infinite loop in tcf_idr_check_alloc() (CVE-2024-40995)
* kernel: xprtrdma: fix pointer derefs in error cases of rpcrdma_ep_create (CVE-2022-48773)
* kernel: vsock: remove vsock from connected table when connect is interrupted by a signal (CVE-2022-48786)
* kernel: perf: Fix list corruption in perf_cgroup_switch() (CVE-2022-48799)
* kernel: SUNRPC: lock against ->sock changing during sysfs read (CVE-2022-48816)
* kernel: mm: prevent derefencing NULL ptr in pfn_section_valid() (CVE-2024-41055)
* kernel: wifi: mac80211: Avoid address calculations via out of bounds array indexing (CVE-2024-41071)
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.
