USN-4093-1
Vulnerability Summary
Timeline
Description
linux, linux-hwe, linux-azure, linux-gcp, linux-kvm, linux-raspi2, linux-snapdragon vulnerabilities It was discovered that a heap buffer overflow existed in the Marvell Wireless LAN device driver for the Linux kernel. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-10126) Andrei Vlad Lutas and Dan Lutas discovered that some x86 processors incorrectly handle SWAPGS instructions during speculative execution. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2019-1125) It was discovered that the PowerPC dlpar implementation in the Linux kernel did not properly check for allocation errors in some situations. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2019-12614) It was discovered that a NULL pointer dereference vulnerability existed in the Near-field communication (NFC) implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2019-12984) Jann Horn discovered a use-after-free vulnerability in the Linux kernel when accessing LDT entries in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-13233) Jann Horn discovered that the ptrace implementation in the Linux kernel did not properly record credentials in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly gain administrative privileges. (CVE-2019-13272) It was discovered that the Marvell Wireless LAN device driver in the Linux kernel did not properly validate the BSS descriptor. A local attacker could possibly use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-3846)
