89355d12b17a57544c4036152b14969eIt 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.
aa1b2d5e0e41264715ab20ee76ffa47dUbuntu Security Notice 4157-2 - USN-4157-1 fixed vulnerabilities in the Linux kernel for Ubuntu 19.04. 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.
739bbc1907a2787aeff5444c0e073effUbuntu Security Notice 4157-1 - 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. 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.
