Description OSIDB Bzimport 2025-10-28 12:02:26 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ASoC: codecs: wcd937x: set the comp soundwire port correctly

For some reason we endup with setting soundwire port for
HPHL_COMP and HPHR_COMP as zero, this can potentially result
in a memory corruption due to accessing and setting -1 th element of
port_map array.
