Description

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:0725 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: sctp: fail if no bound addresses can be used for a given scope (CVE-2023-1074)

* kernel: NULL pointer dereference in nvmet_tcp_build_iovec (CVE-2023-6356)

* kernel: NULL pointer dereference in nvmet_tcp_execute_request (CVE-2023-6535)

* kernel: NULL pointer dereference in __nvmet_req_complete (CVE-2023-6536)

* kernel: Out-Of-Bounds Read vulnerability in smbCalcSize (CVE-2023-6606)

* kernel: OOB Access in smb2_dump_detail (CVE-2023-6610)

* kernel: use-after-free in IPv4 IGMP (CVE-2023-6932)

* kernel: refcount leak in ctnetlink_create_conntrack() (CVE-2023-7192)

* kernel: drivers/usb/storage/ene_ub6250.c (CVE-2023-45862)
