[USN-4390-1] Linux kernel vulnerabilities

Severity Medium
Affected Packages 56
CVEs 6
Info Packages Vulnerabilities

Several security issues were fixed in the Linux kernel.

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 memory contents previously stored in
microarchitectural special registers after RDRAND, RDSEED, and SGX EGETKEY
read operations on Intel client and Xeon E3 processors may be briefly
exposed to processes on the same or different processor cores. A local
attacker could use this to expose sensitive information. (CVE-2020-0543)

Piotr Krysiuk discovered that race conditions existed in the file system
implementation in the Linux kernel. A local attacker could use this to
cause a denial of service (system crash). (CVE-2020-12114)

It was discovered that the USB susbsystem's scatter-gather implementation
in the Linux kernel did not properly take data references in some
situations, leading to a use-after-free. A physically proximate attacker
could use this to cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2020-12464)

Xiumei Mu discovered that the IPSec implementation in the Linux kernel did
not properly encrypt IPv6 traffic in some situations. An attacker could use
this to expose sensitive information. (CVE-2020-1749)

Dmitry Vyukov discovered that the SELinux netlink security hook in the
Linux kernel did not validate messages in some situations. A privileged
attacker could use this to bypass SELinux netlink restrictions.
(CVE-2020-10751)
