Vulnerabilities > CVE-2018-9415 - Double Free vulnerability in multiple products
Attack vector
LOCAL Attack complexity
LOW Privileges required
LOW Confidentiality impact
HIGH Integrity impact
HIGH Availability impact
HIGH Summary
In driver_override_store and driver_override_show of bus.c, there is a possible double free due to improper locking. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Product: Android Versions: Android kernel Android ID: A-69129004 References: Upstream kernel.

NASL family Ubuntu Local Security Checks NASL id UBUNTU_USN-3752-2.NASL description USN-3752-1 fixed vulnerabilities in the Linux kernel for Ubuntu 18.04 LTS. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 18.04 LTS for Ubuntu 16.04 LTS. It was discovered that, when attempting to handle an out-of-memory situation, a NULL pointer dereference could be triggered in the Linux kernel in some circumstances. A local attacker could use this to cause a denial of service (system crash). (CVE-2018-1000200) Wen Xu discovered that the XFS filesystem implementation in the Linux kernel did not properly validate meta-data information. An attacker could use this to construct a malicious xfs image that, when mounted, could cause a denial of service (system crash). (CVE-2018-10323) Wen Xu discovered that the XFS filesystem implementation in the Linux kernel did not properly validate xattr information. An attacker could use this to construct a malicious xfs image that, when mounted, could cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-10840) Wen Xu discovered that the ext4 filesystem implementation in the Linux kernel did not properly keep meta-data information consistent in some situations. An attacker could use this to construct a malicious ext4 image that, when mounted, could cause a denial of service (system crash). (CVE-2018-10881) Wen Xu discovered that the ext4 filesystem implementation in the Linux kernel did not properly handle corrupted meta data in some situations. An attacker could use this to specially craft an ext4 filesystem that caused a denial of service (system crash) when mounted.
