The remote Ubuntu 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-7194-1 advisory.

    Andy Nguyen discovered that the Bluetooth L2CAP implementation in the Linux kernel contained a type-     confusion error. A physically proximate remote attacker could use this to cause a denial of service     (system crash) or possibly execute arbitrary code. (CVE-2020-12351)

    Andy Nguyen discovered that the Bluetooth A2MP implementation in the Linux kernel did not properly     initialize memory in some situations. A physically proximate remote attacker could use this to expose     sensitive information (kernel memory). (CVE-2020-12352)

    Andy Nguyen discovered that the Bluetooth HCI event packet parser in the Linux kernel did not properly     handle event advertisements of certain sizes, leading to a heap-based buffer overflow. A physically     proximate remote attacker could use this to cause a denial of service (system crash) or possibly execute     arbitrary code. (CVE-2020-24490)

    It was discovered that the CIFS network file system implementation in the Linux kernel did not properly     validate certain SMB messages, leading to an out-of-bounds read vulnerability. An attacker could use this     to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2023-6610)

    Supraja Sridhara, Benedict Schlter, Mark Kuhne, Andrin Bertschi, and Shweta Shinde discovered that the     Confidential Computing framework in the Linux kernel for x86 platforms did not properly handle 32-bit     emulation on TDX and SEV. An attacker with access to the VMM could use this to cause a denial of service     (guest crash) or possibly execute arbitrary code. (CVE-2024-25744)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-402244 advisory.

    In the Linux kernel, the following vulnerability has been resolved:

    nilfs2: fix potential null-ptr-deref in nilfs_btree_insert()

    Patch series nilfs2: fix potential issues with empty b-tree nodes.

    This series addresses three potential issues with empty b-tree nodes that     can occur with corrupted filesystem images, including one recently     discovered by syzbot.


    This patch (of 3):

    If a b-tree is broken on the device, and the b-tree height is greater than     2 (the level of the root node is greater than 1) even if the number of     child nodes of the b-tree root is 0, a NULL pointer dereference occurs in     nilfs_btree_prepare_insert(), which is called from nilfs_btree_insert().

    This is because, when the number of child nodes of the b-tree root is 0,     nilfs_btree_do_lookup() does not set the block buffer head in any of     path[x].bp_bh, leaving it as the initial value of NULL, but if the level     of the b-tree root node is greater than 1, nilfs_btree_get_nonroot_node(),     which accesses the buffer memory of path[x].bp_bh, is called.

    Fix this issue by adding a check to nilfs_btree_root_broken(), which     performs sanity checks when reading the root node from the device, to     detect this inconsistency.

    Thanks to Lizhi Xu for trying to solve the bug and clarifying the cause     early on.
