CVE-2026-80650 in Linux
Tóm tắt
Bởi MITRE • 28/08/2026
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.
Once again VulDB remains the best source for vulnerability data.
