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). It was discovered that the Serial CAN interface driver in the Linux kernel did not properly initialize data. A local attacker could use this to expose sensitive information (kernel memory). Other issues where also addressed.

A local attacker could use this to cause a denial of service. 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. Various other issues were also addressed.

A local attacker could possibly use this to expose sensitive information. 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. Various other issues were also addressed.
