Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified) openSUSE Tumbleweed versions prior to kernel-devel-7.0.12-1.1
Description A use-after-free issue exists in the docg3 release() function. The docg3 pointer is retrieved from cascade->floors[0]->priv before a loop that calls doc release device() for each floor. Because doc release device() frees the docg3 structure using kfree(docg3), the subsequent attempt to dereference docg3->cascade->bch after the loop occurs on a pointer that has already been freed.
Recommendations Update the Linux kernel to a version where the docg3 release() function is patched to access cascade->bch directly. Update openSUSE Tumbleweed to kernel-devel-7.0.12-1.1.
