CVE-2026-80624

Summary
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.
