Vulnerability from github – Published: 2026-01-13 18:31 – Updated: 2026-01-13 18:31

Details

In the Linux kernel, the following vulnerability has been resolved:

RDMA/bnxt_re: Fix OOB write in bnxt_re_copy_err_stats()

Commit ef56081d1864 ("RDMA/bnxt_re: RoCE related hardware counters update") added three new counters and placed them after BNXT_RE_OUT_OF_SEQ_ERR.

BNXT_RE_OUT_OF_SEQ_ERR acts as a boundary marker for allocating hardware statistics with different num_counters values on chip_gen_p5_p7 devices.

As a result, BNXT_RE_NUM_STD_COUNTERS are used when allocating hw_stats, which leads to an out-of-bounds write in bnxt_re_copy_err_stats().

The counters BNXT_RE_REQ_CQE_ERROR, BNXT_RE_RESP_CQE_ERROR, and BNXT_RE_RESP_REMOTE_ACCESS_ERRS are applicable to generic hardware, not only p5/p7 devices.

Fix this by moving these counters before BNXT_RE_OUT_OF_SEQ_ERR so they are included in the generic counter set.
