CVE-2024-50300: regulator: rtq2208: Fix uninitialized use of regulator_config
In the Linux kernel, the following vulnerability has been resolved:
regulator: rtq2208: Fix uninitialized use of regulator_config
Fix rtq2208 driver uninitialized use to cause kernel error.
Security readout for executives and security teams
Plain-English summary
A Linux kernel driver for the Richtek RTQ2208 regulator used an incompletely initialized configuration structure, which could trigger kernel errors. The supplied CVSS score is 7.8 because a local, low-privileged attacker may potentially affect confidentiality, integrity, and availability. Actual exposure depends on the vulnerable driver being present and relevant to the system.
Executive priority
Treat as high priority where RTQ2208 hardware or driver use is confirmed, especially on operationally sensitive devices. Use normal risk-based scheduling elsewhere after verifying applicability. There is no supplied evidence of active exploitation, so urgency should be driven by confirmed exposure and the business impact of kernel failure.
Technical view
CVE-2024-50300 is a CWE-908 uninitialized-resource issue in the Linux rtq2208 regulator driver. The cited kernel commits initialize regulator_config before use. The bundle identifies affected Linux 6.6-era and later versions, but its flattened version data does not preserve reliable range boundaries; confirm fixes through kernel or distribution advisories.
Likely exposure
Exposure is likely concentrated in Linux systems that include and use the RTQ2208 regulator driver, particularly relevant embedded or hardware-specific deployments. General-purpose Linux systems without this driver or corresponding hardware may not be practically exposed. The supplied data is insufficient to identify affected distribution packages precisely.
Exploitation context
The CVSS vector describes local access, low attack complexity, low privileges, and no user interaction. However, the supplied sources only document an uninitialized-use kernel error. CVE-2024-50300 is not listed as KEV in the bundle, and no cited evidence establishes active exploitation or a public working exploit.
Researcher notes
The record attributes the fault to uninitialized regulator_config use and supplies three stable-tree fixes. It does not establish the exact trigger, reachable fields, reliable exploitation, or distribution package boundaries. Researchers should avoid extrapolating complete compromise solely from CVSS and should compare vendor kernels against the cited commits.
Mitigation direction
Identify systems running affected Linux kernel branches and determine whether the RTQ2208 driver is included or active.
Apply a vendor-supported kernel update that incorporates the cited upstream stable fix.
Consult distribution or device-vendor advisories for exact patched package versions.
Prioritize relevant embedded or appliance systems where kernel faults could disrupt critical operations.
Validation and detection
Record each system's kernel and distribution package versions.
Check kernel configuration, loaded modules, and hardware inventory for RTQ2208 driver relevance.
Map vendor package changelogs to the cited upstream fix commits.
After updating, confirm the running kernel changed and monitor logs for RTQ2208-related errors.

Use of Uninitialized Resource
Use of Uninitialized Resource represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
