Linux: Use of Uninitialized Resource
CVE-2024-57912 is a high-severity use of uninitialized resource vulnerability in Linux, with a CVSS 3.1 base score of 7.1 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists versions 9629ff1a86823269b12fb1ba9ca4efa945906287, d25f1fc273670271412a52a1efbdaf5dcf274ed8, 64a989aa7475b8e76e69b9ec86819ea293e53bab as the first without the flaw, so updating Linux to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.27% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Linux to 9629ff1a86823269b12fb1ba9ca4efa945906287 or d25f1fc273670271412a52a1efbdaf5dcf274ed8 or 64a989aa7475b8e76e69b9ec86819ea293e53bab or b7849f62e61242e0e02c776e1109eb81e59c567c, whichever matches your release line, or a later version.
- Update Linux Kernel to 6.1.125 or 6.6.72 or 6.12.10, whichever matches your release line, or a later version.

Official description
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.

The underlying weakness: Use of Uninitialized Resource
The product uses or accesses a resource that has not been initialized.
How developers prevent this class of flaw
- Explicitly initialize the resource before use. If this is performed through an API function or standard procedure, follow all required steps.
- Pay close attention to complex conditionals that affect initialization, since some branches might not perform the initialization.
- Avoid race conditions (CWE-362) during initialization routines.

- CISA published its SSVC assessment (exploitation: none, automatable: no, technical impact: partial).
- Record last changed materially (score, affected products, status or references).
