The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2024:1712263970 advisory.

  - A use-after-free flaw was found in the Linux kernel's SGI GRU driver in the way the first     gru_file_unlocked_ioctl function is called by the user, where a fail pass occurs in the     gru_check_chiplet_assignment function. This flaw allows a local user to crash or potentially escalate     their privileges on the system. (CVE-2022-3424)

  - A vulnerability has been found in Linux Kernel and classified as critical. Affected by this vulnerability     is the function area_cache_get of the file drivers/net/ethernet/netronome/nfp/nfpcore/nfp_cppcore.c of the     component IPsec. The manipulation leads to use after free. It is recommended to apply a patch to fix this     issue. The identifier VDB-211045 was assigned to this vulnerability. (CVE-2022-3545)

  - The Linux kernel before 5.18.13 lacks a certain clear operation for the block starting symbol (.bss). This     allows Xen PV guest OS users to cause a denial of service or gain privileges. (CVE-2022-36123)

  - A flaw was found in the Linux kernel. A NULL pointer dereference may occur while a slip driver is in     progress to detach in sl_tx_timeout in drivers/net/slip/slip.c. This issue could allow an attacker to     crash the system or leak internal kernel information. (CVE-2022-41858)

  - There are use-after-free vulnerabilities in the Linux kernel's net/bluetooth/l2cap_core.c's l2cap_connect     and l2cap_le_connect_req functions which may allow code execution and leaking kernel memory (respectively)     remotely via Bluetooth. A remote attacker could execute code leaking kernel memory via Bluetooth if within     proximity of the victim. We recommend upgrading past commit https://www.google.com/url     https://github.com/torvalds/linux/commit/711f8c3fb3db61897080468586b970c87c61d9e4     https://www.google.com/url (CVE-2022-42896)

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

The remote Ubuntu 20.04 LTS / 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6416-1 advisory.

    It was discovered that the IPv6 implementation in the Linux kernel contained a high rate of hash     collisions in connection lookup table. A remote attacker could use this to cause a denial of service     (excessive CPU consumption). (CVE-2023-1206)

    Daniel Trujillo, Johannes Wikner, and Kaveh Razavi discovered that some AMD processors utilising     speculative execution and branch prediction may allow unauthorised memory reads via a speculative side-     channel attack.

    (CVE-2023-3863)

    Laurence Wit discovered that the KSMBD implementation in the Linux kernel did not properly validate a     buffer size in certain situations, leading to an out-of-bounds read vulnerability.

    Maxim Suhanov discovered that the exFAT file system implementation in the Linux kernel did not properly     check a file name length, leading to an out- of-bounds write vulnerability. An attacker could use this to     construct a malicious exFAT image that, when mounted and operated on, could cause a denial of service     (system crash) or possibly execute arbitrary code. (CVE-2023-4273)

    Thelford Williams discovered that the Ceph file system messenger protocol implementation in the Linux     kernel did not properly validate frame segment length in certain situation, leading to a buffer overflow     vulnerability.
