CVE-2026-93147

A flaw was found in the kernel. The s390/bpf component incorrectly handles the loading of a 32-bit CPU number cpunr into a 64-bit BPF register BPFREG0. The ly instruction, used for this operation, fails to clear the upper bits of the 64-bit register. This oversight could lead to the unintended...
