Description OSIDB Bzimport 2026-07-24 16:02:25 UTC
In the Linux kernel, the following vulnerability has been resolved:

phy: qcom: qmp-usbc: Fix out-of-bounds array access in dp swing config

swing_tbl and pre_emphasis_tbl are 4x4 arrays (valid indices 0-3), but
the boundary check uses "> 4" instead of ">= 4", allowing index 4 to
cause an out-of-bounds access.
