CVE-2026-74297Source published Source updated
In the Linux kernel, the following vulnerability has been resolved: RDMA/mlx5: Fix undefined shift of user RQ WQE size set_rq_size() computes the RQ WQE size as "1 << rq_wqe_shift" based on the user-provided rq_wqe_shift, which is only checked to be greater than 32, so shifts of 32 are still accepted. A shift of 31 also overflows a signed integer, leading to undefined behavior. Use check_shl_overflow() to compute the RQ WQE size and reject any invalid values. Insufficient validation of a user-provided input, rq_wqe_shift, in the set_rq_size() function can lead to an integer overflow. This overflow results in an undefined shift operation, which may cause system instability or a denial of service. Red Hat severity: Moderate — CVSS 5.5 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H).…
