    High [CVE-2026-68171] Ensure saved x0 is kept in-sync with tracer updates

    CVE-2026-68171Source published Source updated

    A flaw was found in the Linux kernel's arm64 syscall handling. A local attacker with the ability to trace processes (using ptrace) could manipulate syscall arguments after security checks (like seccomp, or secure computing mode) have been performed. This occurs because the kernel's internal record of the first syscall argument (x0) is not updated when a tracer modifies the actual register, leading to security mechanisms observing outdated information. This could potentially allow a bypass of security policies or lead to incorrect auditing. Red Hat severity: Important — CVSS 7 (CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H). Weakness: CWE-807. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9; Red Hat OpenShift Container Platform…
