CVE-2026-53110 Details
Description
In the Linux kernel, the following vulnerability has been resolved: s390/bpf: Zero-extend bpf prog return values and kfunc arguments s390x ABI requires callers to zero-extend unsigned arguments and sign-extend signed arguments, and callees to zero-extend unsigned return values and sign-extend signed return values. s390 BPF JIT currently implements only sign extension. Fix this omission and implement zero extension too.
A vulnerability in the Linux kernel's s390 BPF Just-In-Time (JIT) compiler has been addressed. The issue arose because the s390x Application Binary Interface (ABI) requires specific handling of argument and return value extensions, which the BPF JIT did not fully implement. The vulnerability existed in several versions of the Linux kernel.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been fixed.
