HighCVSS 7.1/10Last modified Jun 17, 2026

Description

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

ntb: ntb_hw_switchtec: Fix shift-out-of-bounds for 0 mw lut

Number of MW LUTs depends on NTB configuration and can be set to zero, in such scenario rounddown_pow_of_two will cause undefined behaviour and should not be performed. This patch ensures that rounddown_pow_of_two is called on valid value.
