Summary

An issue was discovered in the Linux kernel before 5.0.10. SMB2_negotiate in fs/cifs/smb2pdu.c has an out-of-bounds read because data structures are incompletely updated after a change from smb30 to smb21.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Overread Buffers
    An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.

    descriptionIt was discovered that the RSI 91x Wi-Fi driver in the Linux kernel did not did not handle detach operations correctly, leading to a use-after-free vulnerability. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-21008) Wen Huang discovered that the Marvell Wi-Fi device driver in the Linux kernel did not properly perform bounds checking, leading to a heap overflow. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-14814, CVE-2019-14815, CVE-2019-14816) Matt Delco discovered that the KVM hypervisor implementation in the Linux kernel did not properly perform bounds checking when handling coalesced MMIO write operations. A local attacker with write access to /dev/kvm could use this to cause a denial of service (system crash). (CVE-2019-14821) Hui Peng and Mathias Payer discovered that the USB audio driver for the Linux kernel did not properly validate device meta data. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2019-15117) Hui Peng and Mathias Payer discovered that the USB audio driver for the Linux kernel improperly performed recursion while handling device meta data. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2019-15118) It was discovered that the Technisat DVB-S/S2 USB device driver in the Linux kernel contained a buffer overread. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2019-15505) Brad Spengler discovered that a Spectre mitigation was improperly implemented in the ptrace susbsystem of the Linux kernel. A local attacker could possibly use this to expose sensitive information. (CVE-2019-15902) It was discovered that the SMB networking file system implementation in the Linux kernel contained a buffer overread. An attacker could use this to expose sensitive information (kernel memory). (CVE-2019-15918). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
