Packages

  • linux-gke-5.0 - Linux kernel for Google Container Engine (GKE) systems
  • linux-gke-5.3 - Linux kernel for Google Container Engine (GKE) systems

  • linux-raspi2-5.3 - Linux kernel for Raspberry Pi (V8) systems

Details

Hadar Manor discovered that the DCCP protocol implementation in the Linux
kernel improperly handled socket reuse, leading to a use-after-free
vulnerability. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2020-16119)

Giuseppe Scrivano discovered that the overlay file system in the Linux
kernel did not properly perform permission checks in some situations. A
local attacker could possibly use this to bypass intended restrictions and
gain read access to restricted files. (CVE-2020-16120)
