A memory leak in the nfp_abm_u32_knode_replace() function in drivers/net/ethernet/netronome/nfp/abm/cls.c in the Linux kernel before 5.3.6 allows attackers to cause a denial of service (memory consumption), aka CID-78beef629fd9. NOTE: This has been argued as not a valid vulnerability. The upstream commit 78beef629fd9 was reverted

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-003812 advisory.

The remote Ubuntu 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4209-1 advisory.

    Jann Horn discovered that the OverlayFS and ShiftFS Drivers in the Linux kernel did not properly handle     reference counting during memory mapping operations when used in conjunction with AUFS. A local attacker     could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
    (CVE-2019-15794)

    It was discovered that a buffer overflow existed in the 802.11 Wi-Fi configuration interface for the Linux     kernel when handling beacon settings. A local attacker could use this to cause a denial of service (system     crash) or possibly execute arbitrary code. (CVE-2019-16746)

    It was discovered that there was a memory leak in the Advanced Buffer Management functionality of the     Netronome NFP4000/NFP6000 NIC Driver in the Linux kernel during certain error scenarios. A local attacker     could use this to cause a denial of service (memory exhaustion). (CVE-2019-19076)
