Arbitrary Code Execution

xen is vulnerable to arbitrary code execution. The vulnerability exists as an issue was discovered in Xen through 4.13.x, allowing guest OS users to cause a denial of service or possibly gain privileges because of missing memory barriers in read-write unlock paths. The read-write unlock paths don...

kernel: Indirect Branch Prediction Barrier is force-disabled when STIBP is unavailable or enhanced IBRS is available.

A flaw was found in the Linux kernel’s implementation of the Enhanced IBPB Indirect Branch Prediction Barrier. The IBPB mitigation will be disabled when STIBP is not available or when the Enhanced Indirect Branch Restricted Speculation IBRS is available. This flaw allows a local attacker to perfo...

kernel: Rogue cross-process SSBD shutdown. Linux scheduler logical bug allows an attacker to turn off the SSBD protection.

A logic bug flaw was found in the Linux kernel’s implementation of SSBD. A bug in the logic handling allows an attacker with a local account to disable SSBD protection during a context switch when additional speculative execution mitigations are in place. This issue was introduced when the per...
