Описание
In the Linux kernel, the following vulnerability has been resolved: RISC-V: KVM: fix stack overrun when loading vlenb The userspace load can put up to 2048 bits into an xlen bit stack buffer. We want only xlen bits, so check the size beforehand.
Отчет
This vulnerability does not affect Red Hat Enterprise Linux as the affected RISC-V virtualization code is not supported or present in shipped kernels. The flaw exists exclusively in the KVM implementation for RISC-V platforms when processing vector extension registers. Supported Red Hat hardware architectures are therefore not exposed to this flaw.
