Description

linux-hwe, linux-gke-5.0, linux-gke-5.3, linux-oem-osp1, linux-raspi2-5.3 vulnerabilities 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)
