  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\nplatform/x86: dell-wmi-sysman: Don't hex dump plaintext password data\nset_new_password() hex dumps the entire buffer, which contains plaintext\npassword data, including current and new passwords. Remove the hex dump\nto avoid leaking credentials.", "A flaw was found in the dell-wmi-sysman component of the Linux kernel. This vulnerability occurs because the set_new_password() function incorrectly hex dumps the entire buffer, which includes sensitive plaintext password data. A local attacker could exploit this to disclose user credentials, leading to unauthorized access." ],
  "statement" : "This flaw affects Dell systems using the dell-wmi-sysman driver for BIOS password management. The debug hex dump exposes plaintext current and new passwords to kernel logs (dmesg). A local user with access to kernel logs could retrieve BIOS passwords. This is an information disclosure issue rather than code execution.",
