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.
14f02287095aa69b1f4a060649c3f887Ubuntu Security Notice 4392-1 - It was discovered that the Marvell WiFi-Ex Driver in the Linux kernel did not properly validate status lengths in messages received from an access point, leading to a buffer overflow. A physically proximate attacker controlling an access point could use this to construct messages that could possibly result in arbitrary code execution. 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.

3cd7fbe81c4015ba8baf954c820314b8Ubuntu Security Notice 4391-1 - It was discovered that the ext4 file system implementation in the Linux kernel did not properly handle setxattr operations in some situations. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. 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.
