- Summary
- CVE-2025-40035 affecting package kernel for versions less than 6.6.112.1-2
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
Input: uinput - zero-initialize uinput_ff_upload_compat to avoid info leak
Struct ff_effect_compat is embedded twice inside uinput_ff_upload_compat, contains internal padding. In particular, there is a hole after struct ff_replay to satisfy alignment requirements for the following union member. Without clearing the structure, copy_to_user() may leak stack data to userspace.
Initialize ff_up_compat to zero before filling valid fields.
