CVE-2024-50072

CVE-2024-50072 affects the Linux kernel on x86 where VERW is used. The issue can trigger a general protection fault (#GP) in 32-bit vm86 contexts when VERW mitigations (e.g., MDS/RFDS) are enabled and the code segment selector is not properly referenced. The root cause is using VERW with an arbit...

A flaw was found in the fix for CVE-2019-11135 in the Linux upstream kernel versions before 5.5 where the way Intel CPUs handle speculative execution of instructions when a TSX Asynchronous Abort (TAA) error occurs. When a guest is running on a host CPU affected by the TAA flaw (TAA_NO=0) but is not affected by the MDS issue (MDS_NO=1) the guest was to clear the affected buffers by using a VERW instruction mechanism. But when the MDS_NO=1 bit was exported to the guests the guests did not use the VERW mechanism to clear the affected buffers. This issue affects guests running on Cascade Lake CPUs and requires that host has 'TSX' enabled. Confidentiality of data is the highest threat associated with this vulnerability.
