What to do
AI-suggested
A fix is available that replaces kmalloc() with kzalloc() for memory allocation in the affected code, ensuring memory is zero-initialized before use. Users should apply the official Linux kernel patches that address this issue once they are released. Until patched, restricting local access and privileges can reduce risk.
Description
CVE-2024-57911 is a high-severity vulnerability in the Linux kernel's Industrial I/O (iio) subsystem, specifically in the dummy driver. The flaw involves an information leak caused by uninitialized memory being pushed to user space from a triggered buffer. This occurs because the data array allocated with kmalloc() does not initialize values for inactive channels, potentially exposing sensitive kernel memory contents.
