UBUNTU-CVE-2024-57912: Medium severity ubuntu/linux-azure vulnerability
In the Linux kernel, the following vulnerability has been resolved: iio: pressure: zpa2326: fix information leak in triggered buffer The 'sample' local struct is used to push data to user space from a triggered buffer, but it has a hole between the temperature and the timestamp (u32 pressure, u16 temperature, GAP, u64 timestamp). This hole is never initialized. Initialize the struct to zero before using it to avoid pushing uninitialized information to userspace.

Zero-initialize the local `sample` struct before using it to push triggered-buffer data to userspace, ensuring the padding hole between the temperature and timestamp fields does not contain uninitialized information.
Event History
Frequently Asked Questions
Who is exposed to this issue?
Systems running an affected Ubuntu Linux kernel variant that use the ZPA2326 pressure sensor driver with its triggered buffer can expose uninitialized kernel information to local userspace.
What access does an attacker need?
The issue has local attack vector and requires low privileges. No user interaction is required.
What data can be disclosed?
The uninitialized gap between the temperature field and timestamp in triggered-buffer samples may disclose unintended kernel information when the sample is pushed to userspace.
Which Ubuntu kernel packages are listed as affected?
The listed software includes ubuntu/linux, ubuntu/linux-fips, ubuntu/linux-azure, ubuntu/linux-aws-fips, ubuntu/linux-azure-fips, ubuntu/linux-gcp-fips, ubuntu/linux-gcp, and ubuntu/linux-oracle.
