Intel CPUs Vulnerable to New 'SGAxe' and 'CrossTalk' Side-Channel Attacks

Cybersecurity researchers have discovered two distinct attacks that could be exploited against modern Intel processors to leak sensitive information from the CPU's trusted execution environments TEE. Called SGAxe, the first of the flaws is an evolution of the previously uncovered CacheOut attack...

USN-4393-1: Linux kernel vulnerabilities

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...

Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS : Intel Microcode vulnerabilities (USN-4385-1)

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4385-1 advisory. It was discovered that memory contents previously stored in microarchitectural special registers after RDRAND, RDSEED, and SGX...

Ubuntu 18.04 LTS : Linux kernel vulnerabilities (USN-4388-1)

The remote Ubuntu 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4388-1 advisory. 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...

USN-4385-1: Intel Microcode vulnerabilities

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 th...

Updated mbedtls packages fix security vulnerabilities

Updated mbedtls packages fix security vulnerabilities: If Mbed TLS is running in an SGX enclave and the adversary has control of the main operating system, they can launch a side channel attack to recover the RSA private key when it is being imported. Found by Alejandro Cabrera Aldaya and Billy...
