Synopsis
The remote Red Hat host is missing one or more security updates for kpatch-patch.Description
The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:1435 advisory.- A vulnerability classified as critical was found in Linux Kernel. Affected by this vulnerability is the function l2cap_reassemble_sdu of the file net/bluetooth/l2cap_core.c of the component Bluetooth. The manipulation leads to use after free. It is recommended to apply a patch to fix this issue. The associated identifier of this vulnerability is VDB-211087. (CVE-2022-3564)
- A stack overflow flaw was found in the Linux kernel's SYSCTL subsystem in how a user changes certain kernel parameters and variables. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-4378)
- A use-after-free vulnerability was found in __nfs42_ssc_open() in fs/nfs/nfs4file.c in the Linux kernel.
This flaw allows an attacker to conduct a remote denial (CVE-2022-4379)
- A buffer overflow vulnerability was found in the Netfilter subsystem in the Linux Kernel. This issue could allow the leakage of both stack and heap addresses, and potentially allow Local Privilege Escalation to the root user via arbitrary code execution. (CVE-2023-0179)
- A use after free vulnerability exists in the ALSA PCM package in the Linux Kernel.
SNDRV_CTL_IOCTL_ELEM_{READ|WRITE}32 is missing locks that can be used in a use-after-free that can result in a priviledge escalation to gain ring0 access from the system user. We recommend upgrading past commit 56b88b50565cd8b946a2d00b0c83927b7ebb055e (CVE-2023-0266)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Update the RHEL kpatch-patch package based on the guidance in RHSA-2023:1435.See Also
