CVE-2024-38540

In the Linux kernel, the following vulnerability has been resolved: bnxtre: avoid shift undefined behavior in bnxtqpliballocinithwq Undefined behavior is triggered when bnxtqpliballocinithwq is called with hwqattr-auxdepth != 0 and hwqattr-auxstride == 0. In that case,...

CVE-2024-38540

CVE-2024-38540 concerns the Linux kernel bnxt_re driver. The vulnerability is due to undefined behavior triggered when bnxt_qplib_alloc_init_hwq is called with hwq_attr->aux_depth != 0 and hwq_attr->aux_stride == 0, which causes roundup_pow_of_two(hwq_attr->aux_stride) to run with a 0 va...
