Description

A flaw was found in the Linux kernel's Compute Express Link (CXL) subsystem. This vulnerability allows a local user to cause a Denial of Service (DoS) or system instability through an out-of-bounds memory access. During CXL region configuration, the kernel fails to validate that the partition index is non-negative before indexing an internal array, resulting in an out-of-bounds read if the partition is unresolved.
