The remote Redhat Enterprise Linux 9 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2023:0348 advisory.

A race condition was found in the Linux kernel’s watch queue due to a missing lock in pipe_resize_ring().
The specific flaw exists within the handling of pipe buffers. The issue results from the lack of proper locking when performing operations on an object. This flaw allows a local user to crash the system or escalate their privileges on the system. (CVE-2022-2959)
A flaw was found in the Linux kernel’s driver for the ASIX AX88179_178A-based USB 2.0/3.0 Gigabit Ethernet Devices. The vulnerability contains multiple out-of-bounds reads and possible out-of-bounds writes.
(CVE-2022-2964)
An incorrect TLB flush issue was found in the Linux kernel’s GPU i915 kernel driver, potentially leading to random memory corruption or data leaks. This flaw could allow a local user to crash the system or escalate their privileges on the system. (CVE-2022-4139)
The Linux kernel NFSD implementation prior to versions 5.19.17 and 6.0.2 are vulnerable to buffer overflow. NFSD tracks the number of pages held by each NFSD thread by combining the receive and send buffers of a remote procedure call (RPC) into a single array of pages. A client can force the send buffer to shrink by sending an RPC message over TCP with garbage data added at the end of the message. The RPC message with garbage data is still correctly formed according to the specification and is passed forward to handlers. Vulnerable code in NFSD is not expecting the oversized request and writes beyond the allocated buffer space. CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H (CVE-2022-43945)

Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
