linux-gke-5.0, linux-oem-osp11 vulnerabilities

Published Apr 28, 2020 · Updated Jun 3, 2026

Summary

It was discovered that the Intel Wi-Fi driver in the Linux kernel did not
properly check for errors in some situations. A local attacker could
possibly use this to cause a denial of service (system crash).
(CVE-2019-16234)

It was discovered that the Intel WiMAX 2400 driver in the Linux kernel did
not properly deallocate memory in certain situations. A local attacker
could use this to cause a denial of service (kernel memory exhaustion).
(CVE-2019-19051)

Tristan Madani discovered that the block I/O tracing implementation in the
Linux kernel contained a race condition. A local attacker could use this to
cause a denial of service (system crash) or possibly expose sensitive
information. (CVE-2019-19768)

It was discovered that the vhost net driver in the Linux kernel contained a
stack buffer overflow. A local attacker with the ability to perform ioctl()
calls on /dev/vhost-net could use this to cause a denial of service (system
crash). (CVE-2020-10942)

It was discovered that the virtual terminal implementation in the Linux
kernel contained a race condition. A local attacker could possibly use this
to cause a denial of service (system crash) or expose sensitive
information. (CVE-2020-8648)

Shijie Luo discovered that the ext4 file system implementation in the Linux
kernel did not properly check for a too-large journal size. An attacker
could use this to construct a malicious ext4 image that, when mounted,
could cause a denial of service (soft lockup). (CVE-2020-8992)

Jordy Zomer discovered that the floppy driver in the Linux kernel did not
properly check for errors in some situations. A local attacker could
possibly use this to cause a denial of service (system crash) or possibly
expose sensitive information. (CVE-2020-9383)
