Note that Nessus relies on the presence of the package as reported by the vendor.

The version of kernel installed on the remote host is prior to 5.15.90-54.138. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.15-2023-013 advisory.

    In the Linux kernel before 6.1.6, a NULL pointer dereference bug in the traffic control subsystem allows     an unprivileged user to trigger a denial of service (system crash) via a crafted traffic control     configuration that is set up with tc qdisc and tc class commands. This affects qdisc_graft in     net/sched/sch_api.c. (CVE-2022-47929)

    The Linux kernel does not correctly mitigate SMT attacks, as discovered through a strange pattern in the     kernel API using STIBP as a mitigation, leaving the process exposed for a short period of time after a     syscall. The kernel also does not issue an IBPB immediately during the syscall. (CVE-2023-0045)

    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 NULL pointer dereference flaw was found in rawv6_push_pending_frames in net/ipv6/raw.c in the network     subcomponent in the Linux kernel. This flaw causes the system to crash. (CVE-2023-0394)

    Detected a few exploitable gadgets that could leak secret memory through a side-channel such as MDS as     well as insufficient hardening of the usercopy functions against spectre-v1. (CVE-2023-0459)

    There is a use-after-free vulnerability in the Linux Kernel which can be exploited to achieve local     privilege escalation. To reach the vulnerability kernel configuration flag CONFIG_TLS or     CONFIG_XFRM_ESPINTCP has to be configured, but the operation does not require any privilege.

    There is a use-after-free bug of icsk_ulp_data of a struct inet_connection_sock.

    When CONFIG_TLS is enabled, user can install a tls context (struct tls_context) on a connected tcp socket.
    The context is not cleared if this socket is disconnected and reused as a listener. If a new socket is     created from the listener, the context is inherited and vulnerable.

    The setsockopt TCP_ULP operation does not require any privilege.

    We recommend upgrading past commit 2c02d41d71f90a5168391b6a5f2954112ba2307c (CVE-2023-0461)

(CVE-2023-23454)

    atm_tc_enqueue in net/sched/sch_atm.c in the Linux kernel through 6.1.4 allows attackers to cause a denial     of service because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition     rather than valid classification results). (CVE-2023-23455)

    In the Linux kernel 6.0.8, there is a use-after-free in run_unpack in fs/ntfs3/run.c, related to a     difference between NTFS sector size and media sector size. (CVE-2023-26544)
