The remote Ubuntu 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6057-1 advisory.
A flaw was found in the Linux kernel’s Layer 2 Tunneling Protocol (L2TP). A missing lock when clearing sk_user_data can lead to a race condition and NULL pointer dereference. A local user could use this flaw to potentially crash the system causing a denial of service. (CVE-2022-4129)
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)
A flaw NULL Pointer Dereference in the Linux kernel NTFS3 driver function attr_punch_hole() was found. A local user could use this flaw to crash the system. (CVE-2022-4842)
A flaw was found in the Linux kernel, where unauthorized access to the execution of the setuid file with capabilities was found in the Linux kernel’s OverlayFS subsystem in how a user copies a capable file from a nosuid mount into another mount. This uid mapping bug allows a local user to escalate their privileges on the system. (CVE-2023-0386)
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)
A memory corruption flaw was found in the Linux kernel’s human interface device (HID) subsystem in how a user inserts a malicious USB device. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2023-1073)
A memory leak flaw was found in the Linux kernel’s Stream Control Transmission Protocol. This issue may occur when a user starts a malicious networking service and someone connects to this service. This could allow a local user to starve resources, causing a denial of service. (CVE-2023-1074)
Use After Free vulnerability in Linux kernel traffic control index filter (tcindex) allows Privilege Escalation. The imperfect hash area can be updated while packets are traversing, which will cause a use- after-free when ‘tcf_exts_exec()’ is called with the destroyed tcf_ext. A local attacker user can use this vulnerability to elevate its privileges to root. This issue affects Linux Kernel: from 4.14 before git commit ee059170b1f7e94e55fa6cadee544e176a6e59c2. (CVE-2023-1281)
A use-after-free flaw was found in nfsd4_ssc_setup_dul in fs/nfsd/nfs4proc.c in the NFS filesystem in the Linux Kernel. This issue could allow a local attacker to crash the system or it may lead to a kernel information leak problem. (CVE-2023-1652)
In the Linux kernel before 6.1.13, there is a double free in net/mpls/af_mpls.c upon an allocation failure (for registering the sysctl table under a new location) during the renaming of a device. (CVE-2023-26545)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
