CVE-2026-64082

A flaw was found in the Linux kernel, specifically within the RISC-V architecture's handling of process tracing and signal restoration. When functions like compat_riscv_gpr_set() or compat_restore_sigcontext() are invoked, they may process uninitialized stack data if a preceding user data copy operation fails. This can lead to the corruption of a task's register state and potentially leak sensitive kernel stack contents, resulting in information disclosure and a denial of service.
