A memory leak in the fastrpc_dma_buf_attach() function in drivers/misc/fastrpc.c in the Linux kernel before 5.3.9 allows attackers to cause a denial of service (memory consumption) by triggering dma_get_sgtable() failures, aka CID-fc739a058d99.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-004068 advisory.

    A memory leak in the fastrpc_dma_buf_attach() function in drivers/misc/fastrpc.c in the Linux kernel     before 5.3.9 allows attackers to cause a denial of service (memory consumption) by triggering     dma_get_sgtable() failures, aka CID-fc739a058d99.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A memory leak in the fastrpc_dma_buf_attach() function in drivers/misc/fastrpc.c in the Linux kernel     before 5.3.9 allows attackers to cause a denial of service (memory consumption) by triggering     dma_get_sgtable() failures, aka CID-fc739a058d99. (CVE-2019-19069)

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

The remote Ubuntu 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4208-1 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)

    Nicolas Waisman discovered that the WiFi driver stack in the Linux kernel did not properly validate SSID     lengths. A physically proximate attacker could use this to cause a denial of service (system crash).
    (CVE-2019-17133)

    It was discovered that the ARM Komeda display driver for the Linux kernel did not properly deallocate     memory in certain error conditions. A local attacker could use this to cause a denial of service (memory     exhaustion). (CVE-2019-18810)

    It was discovered that the VirtualBox guest driver implementation in the Linux kernel did not properly     deallocate memory in certain error conditions. A local attacker could use this to cause a denial of     service (memory exhaustion). (CVE-2019-19048)

    It was discovered that the ADIS16400 IIO IMU Driver for the Linux kernel did not properly deallocate     memory in certain error conditions. A local attacker could use this to cause a denial of service (memory     exhaustion). (CVE-2019-19060, CVE-2019-19061)

    It was discovered that the Intel OPA Gen1 Infiniband Driver for the Linux kernel did not properly     deallocate memory in certain error conditions. A local attacker could use this to cause a denial of     service (memory exhaustion). (CVE-2019-19065)

    It was discovered that the AMD Audio Coprocessor driver for the Linux kernel did not properly deallocate     memory in certain error conditions. A local attacker with the ability to load modules could use this to     cause a denial of service (memory exhaustion). (CVE-2019-19067)

    It was discovered in the Qualcomm FastRPC Driver for the Linux kernel did not properly deallocate memory     in certain error conditions. A local attacker could use this to cause a denial of service (memory     exhaustion). (CVE-2019-19069)

    It was discovered that the Cascoda CA8210 SPI 802.15.4 wireless controller driver for the Linux kernel did     not properly deallocate memory in certain error conditions. A local attacker could use this to cause a     denial of service (memory exhaustion). (CVE-2019-19075)

    It was discovered that the AMD Display Engine Driver in the Linux kernel did not properly deallocate     memory in certain error conditions. A local attack could use this to cause a denial of service (memory     exhaustion). (CVE-2019-19083)

    Nicolas Waisman discovered that the Chelsio T4/T5 RDMA Driver for the Linux kernel performed DMA from a     kernel stack. A local attacker could use this to cause a denial of service (system crash).
