CVE-2026-43241

A flaw was found in the Linux kernel component ntbhwswitchtec. This vulnerability allows an attacker to trigger an array-index-out-of-bounds access when handling the number of MW LUTs, which depends on NTB configuration. This invalid access to mwsizes can lead to a Denial of Service DoS condition...
