Detailsinfo

A vulnerability was found in Linux Kernel up to 6.12.96/6.18.39/7.1.4 and classified as very critical. Affected by this issue is the function gc2235_probe of the component gc2235. The manipulation with an unknown input leads to a use after free vulnerability. Using CWE to declare the problem leads to CWE-416. Referencing memory after it has been freed can cause a program to crash, use unexpected values, or execute code. Impacted is confidentiality, integrity, and availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: media: atomisp: gc2235: fix UAF and memory leak gc2235_probe() handles its error paths incorrectly. If media_entity_pads_init() fails, gc2235_remove() is called, which tears down the subdev and frees dev, but then still falls through to atomisp_register_i2c_module(). This results in use-after-free. If atomisp_register_i2c_module() fails, the media entity and control handler are left initialized and dev is leaked. gc2235_remove() unconditionally calls media_entity_cleanup() and v4l2_ctrl_handler_free(), but these are not initialized at every error path in gc2235_probe(). Replace gc2235_remove() calls in the probe error paths with explicit unwind labels that free only the resources initialized at each point of failure, in reverse order of initialization.

The advisory is available at git.kernel.org. This vulnerability is handled as CVE-2026-80650 since 08/26/2026. The exploitation is known to be easy. The attack may be launched remotely. Technical details are known, but there is no available exploit. The structure of the vulnerability defines a possible price range of USD $5k-$25k at the moment (estimation calculated on 08/28/2026).

Upgrading to version 6.12.97, 6.18.40 or 7.1.5 eliminates this vulnerability. Applying the patch fdbb8e55578b4ab647fa58827a9dd8730d7f4add/d57e67ea48e4d095052f2b14d8dd7593621f862f/f614bf0a64aa1cb7444d152a96798a6bf1d49e1f/628f763aee0047ff44974388d6f70f75a763026b is able to eliminate this problem.
