Linux: Use of Uninitialized Resource
CVE-2024-41059 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 72805debec8f7aa342da194fe0ed7bc8febea335, c733e24a61cbcff10f660041d6d84d32bb7e4cb4, 34f8efd2743f2d961e92e8e994de4c7a2f9e74a0 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 72805debec8f7aa342da194fe0ed7bc8febea335 or c733e24a61cbcff10f660041d6d84d32bb7e4cb4 or 34f8efd2743f2d961e92e8e994de4c7a2f9e74a0 or d02d8c1dacafb28930c39e16d48e40bb6e4cbc70, whichever matches your release line, or a later version.
- Update Linux Kernel to 4.19.319 or 5.4.281 or 5.10.223 or 5.15.164, whichever matches your release line, or a later version.

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.

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