[USN-4527-1] Linux kernel vulnerabilities

Severity Medium
Affected Packages 72
CVEs 8
Info Packages Vulnerabilities

Several security issues were fixed in the Linux kernel.

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)
