CVE-2026-80650

/// Technical description

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.

/// Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
