Description OSIDB Bzimport 2026-08-28 07:45:12 UTC
In the Linux kernel, the following vulnerability has been resolved:

mfd: cs42l43: Sanity check firmware size

Currently the code checks if a firmware was received, however it does
not verify that the firmware size is larger than the firmware header. As
the firmware pointer is dereferenced as a pointer to the header
structure this could lead to an out of bounds memory access. Add the
missing check.
