CVE-2026-74391 tracing: Bound synthetic-field strings with seq_buf

In the Linux kernel, the following vulnerability has been resolved: tracing: Bound synthetic-field strings with seqbuf The synthetic field helpers build a prefixed synthetic variable name and a generated hist command in fixed MAXFILTERSTRVAL buffers. The current code appends those strings with ra...

CVE-2026-74392 dm: limit target bio polling to one shot

In the Linux kernel, the following vulnerability has been resolved: dm: limit target bio polling to one shot dmpollbio is the -pollbio callback for a stacked dm device. The caller only knows about the dm queue, so it may decide to do a spinning poll if it thinks a single queue is being polled...

CVE-2026-74391

In CVE-2026-74391, the Linux kernel tracing subsystem is affected by a buffer-overflow risk in synthetic-field string construction. The vulnerability arises because synthetic field helpers append strings with strcat() to fixed MAX_FILTER_STR_VAL buffers, allowing long key lists, field names, or s...

CVE-2026-74390

CVE-2026-74390 affects the Linux kernel’s RDMA/irdma path. The vulnerability stems from an out-of-bounds write in irdma_copy_user_pgaddrs, which iterates over umem DMA blocks to fill PBLEs. When irdma_setup_pbles is called with lvl==0, the loop may not exit properly if palloc->total_cnt == 0, ...

CVE-2026-74389

Summary: CVE-2026-74389 affects the Linux kernel RDMA driver for HNS (hns_roce). When hns_roce_cmd_mbox() fails, the error path could flood logs due to unlimited ibdev_err/ibdev_warn outputs, potentially leading to a system crash. The fix replaces the non-limited error prints with ratelimited ver...
