CVE-2026-23243 RDMA/umad: Reject negative data_len in ib_umad_write

In the Linux kernel, the following vulnerability has been resolved: RDMA/umad: Reject negative datalen in ibumadwrite ibumadwrite computes datalen from user-controlled count and the MAD header sizes. With a mismatched user MAD header size and RMPP header length, datalen can become negative and...

CVE-2026-23243

CVE-2026-23243 is a Linux kernel vulnerability involving RDMA/umad_write, where user-controlled MAD header size mismatch could yield a negative data_len, leading to an out-of-bounds memset in alloc_send_rmpp_list. The issue has a concrete upstream fix that rejects negative data_len before creatin...

CVE-2026-23242

CVE-2026-23242 affects the Linux kernel RDMA/siw header processing: siw_tcp_rx_data may dereference a NULL qp->rx_fpdu if siw_get_hdr() returns -EINVAL before set_rx_fpdu_context(). The fix adds a NULL check for rx_fpdu before accessing more_ddp_segs, preventing the NULL pointer dereference. P...
