Linux: Use of Uninitialized Resource
CVE-2024-57910 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 13e56229fc81051a42731046e200493c4a7c28ff, b0e9c11c762e4286732d80e66c08c2cb3157b06b, cb488706cdec0d6d13f2895bcdf0c32b283a7cc7 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 0.22% 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 13e56229fc81051a42731046e200493c4a7c28ff or b0e9c11c762e4286732d80e66c08c2cb3157b06b or cb488706cdec0d6d13f2895bcdf0c32b283a7cc7 or 47d245be86492974db3aeb048609542167f56518, whichever matches your release line, or a later version.
- Update Linux Kernel to 5.4.290 or 5.10.234 or 5.13 or 5.15.177, whichever matches your release line, or a later version.

Official description
In the Linux kernel, the following vulnerability has been resolved: iio: light: vcnl4035: fix information leak in triggered buffer The 'buffer' local array is used to push data to userspace from a triggered buffer, but it does not set an initial value for the single data element, which is an u16 aligned to 8 bytes. That leaves at least 4 bytes uninitialized even after writing an integer value with regmap_read(). Initialize the array 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).
