CVE-2024-50193: Linux Kernel

High severity, CVSS 7.1. EPSS: 0.2% chance of exploitation in the next 30 days.

In the Linux kernel, the following vulnerability has been resolved: x86/entry_32: Clear CPU buffers after register restore in NMI return CPU buffers are currently cleared after call to exc_nmi, but before register state is restored. This may be okay for MDS mitigation but not for RDFS. Because RDFS mitigation requires CPU buffers to be cleared when registers don't have any sensitive data. Move CLEAR_CPU_BUFFERS after RESTORE_ALL_NMI.

Affected products
