Synopsis

The remote Red Hat host is missing one or more security updates for kernel-rt.

Description

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:0300 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: watch queue race condition can lead to privilege escalation (CVE-2022-2959)

* kernel: memory corruption in AX88179_178A based USB ethernet device. (CVE-2022-2964)

* kernel: i915: Incorrect GPU TLB flush can lead to random memory access (CVE-2022-4139)

* kernel: nfsd buffer overflow by RPC message over TCP with garbage data (CVE-2022-43945)

* kernel: i2c: unbounded length leads to buffer overflow in ismt_access() (CVE-2022-3077)

* kernel: Unprivileged users may use PTRACE_SEIZE to set PTRACE_O_SUSPEND_SECCOMP option (CVE-2022-30594)

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.

Bug Fix(es):

* DELL EMC: System is not booting into RT Kernel with perc12 [kernel-rt] (BZ#2139863)

* kernel-rt: update RT source tree to the latest RHEL-9.1.z1 Batch (BZ#2141817)
