In the Linux kernel, the following vulnerability has been resolved:
platform/x86: dell-wmi-sysman: Don't hex dump attribute security buffer
set_attribute() populates the security area of the BIOS attribute request
buffer with the current admin password via populate_security_buffer(), then
dumps the whole request buffer with print_hex_dump_bytes(). This can expose
the plaintext admin password in the kernel log.
The same issue was fixed for the password attribute path by
commit d1a196e0a6dc ("platform/x86: dell-wmi-sysman: Don't hex dump
plaintext password data"). Remove the remaining dump from the BIOS
attribute path.
