CVE-2026-72497
Description
A flaw was found in the RDMA/bnxt_re component of the Linux kernel. This vulnerability arises from insufficient validation of the Work Queue Entry (WQE) mode, which dictates how tasks are managed, against the hardware's defined slot limits. A local attacker could exploit this by supplying an invalid WQE mode value, potentially causing unexpected system behavior or a denial of service (DoS).
Statement

Understanding the Weakness (CWE)
Integrity,Confidentiality,Availability
Technical Impact: Read Memory; Modify Memory; Execute Unauthorized Code or Commands
Buffer overflows often can be used to execute arbitrary code, which is usually outside the scope of a program's implicit security policy. This can often be used to subvert any other security service.
Availability
Technical Impact: Modify Memory; DoS: Crash, Exit, or Restart; DoS: Resource Consumption (CPU)
Buffer overflows generally lead to crashes. Other attacks leading to lack of availability are possible, including putting the program into an infinite loop.
