CVE-2025-38077
In the Linux kernel, the following vulnerability has been resolved: platform/x86: dell-wmi-sysman: Avoid buffer overflow in current_password_store() If the 'buf' array received from the user contains an empty string, the 'length' variable will be zero.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.21%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
In the Linux kernel, the following vulnerability has been resolved: platform/x86: dell-wmi-sysman: Avoid buffer overflow in current_password_store() If the 'buf' array received from the user contains an empty string, the 'length' variable will be zero. Accessing the 'buf' array element with index 'length - 1' will result in a buffer overflow. Add a check for an empty string. Found by Linux Verification Center (linuxtesting.org) with SVACE.
