CVE-2026-89532

This is an integer underflow in the Linux kernel's svcrdma (NFS/RDMA server) component. When a parsed chunk has ch_segcount == 0, the pcl_for_each_segment macro computes an inclusive upper bound as &ch_segments[0 - 1], which wraps the u32 to 0xFFFFFFFF, causing the loop to walk unrelated memory a...
