An issue was discovered in the Linux kernel before 6.5.9, exploitable by
local users with userspace access to MMIO registers. Incorrect access
checking in the #VC handler and instruction emulation of the SEV-ES
emulation of MMIO accesses could lead to arbitrary write access to kernel
memory (and thus privilege escalation). This depends on a race condition
through which userspace can replace an instruction before the #VC handler
reads it.
