CVE-2026-90415

CVE-2026-90415 affects the Linux kernel RDMA/cxgb4 driver (Chelsio T4/T5/T6). In write_tpt_entry(), a new STAG index is allocated via c4iw_get_resource() and stats.stag.cur is incremented before programming the TPT entry. When the subsequent write_adapter_mem() call fails, the error is returned w...

CVE-2026-90309 RDMA/erdma: Hold CQ references when processing EQ events

In the Linux kernel, the following vulnerability has been resolved: RDMA/erdma: Hold CQ references when processing EQ events EQ handlers look up CQs from dev-cqxa and invoke CQ completion or error callbacks outside the xarray lock. erdmadestroycq can erase the CQ from the xarray and free its queu...

CVE-2026-90308

CVE-2026-90308 is a use-after-free race condition in the Linux kernel's RDMA/erdma subsystem. AE QP fatal events and iWARP CM paths load queue pairs from dev->qp_xa and then reference them outside the xarray lock, while erdma_destroy_qp() can concurrently free those QP resources. The fix intro...

CVE-2026-90307

CVE-2026-90307 is a heap information disclosure vulnerability in the Linux kernel's RDMA/srp (SCSI RDMA Protocol) subsystem. The root cause is that srp_process_cred_req() and srp_process_aer_req() read fixed-size fields from the receive buffer without verifying that the data was actually present....
