bf62eae52a9e8701d96b669a2f1dc34dbcad875c47ff666c8f00d6add34b28a7It was discovered that a race condition existed in the GFS2 file system in the Linux kernel. A local attacker could possibly use this to cause a denial of service (system crash). It was discovered that a use-after-free error existed in the block layer subsystem of the Linux kernel when certain failure conditions occurred. A local attacker could possibly use this to cause a denial of service (system crash) or possibly execute arbitrary code. Various other issues were also addressed.

This update provides the corresponding updates for the Linux Hardware Enablement kernel from Ubuntu 19.04 for Ubuntu 18.04 LTS. 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 or possibly execute arbitrary code. Various other issues were also addressed.

A local attacker could use this to cause a denial of service or possibly execute arbitrary code. 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. Various other issues were also addressed.
