Summary
It was discovered that the Conexant 23885 TV card device driver for the
Linux kernel did not properly deallocate memory in some error conditions. A
local attacker could use this to cause a denial of service (memory
exhaustion). (CVE-2019-19054)
It was discovered that the Atheros HTC based wireless driver in the Linux
kernel did not properly deallocate in certain error conditions. A local
attacker could use this to cause a denial of service (memory exhaustion).
(CVE-2019-19073, CVE-2019-19074)
Yue Haibing discovered that the Linux kernel did not properly handle
reference counting in sysfs for network devices in some situations. A local
attacker could possibly use this to cause a denial of service.
(CVE-2019-20811)
It was discovered that the F2FS file system in the Linux kernel did not
properly perform bounds checking in some situations, leading to an out-of-
bounds read. A local attacker could possibly use this to expose sensitive
information (kernel memory). (CVE-2019-9445)
It was discovered that the F2FS file system in the Linux kernel did not
properly validate xattr meta data in some situations, leading to an out-of-
bounds read. An attacker could use this to construct a malicious F2FS image
that, when mounted, could expose sensitive information (kernel memory).
(CVE-2019-9453)
It was discovered that the F2FS file system implementation in the Linux
kernel did not properly perform bounds checking on xattrs in some
situations. A local attacker could possibly use this to expose sensitive
information (kernel memory). (CVE-2020-0067)
It was discovered that the NFS client implementation in the Linux kernel
did not properly perform bounds checking before copying security labels in
some situations. A local attacker could use this to cause a denial of
service (system crash) or possibly execute arbitrary code. (CVE-2020-25212)
