CVE-2026-46285

Vulnerability overview

In the Linux kernel, the following vulnerability has been resolved: mtd: docg3: fix use-after-free in docg3_release() In docg3_release(), the docg3 pointer is obtained from cascade->floors[0]->priv before the loop that calls doc_release_device() on each floor. doc_release_device() frees the docg3 struct via kfree(docg3) at line 1881. After the loop, docg3->cascade->bch dereferences the already-freed pointer. Fix this by accessing cascade->bch directly, which is equivalent since docg3->cascade points back to the same cascade struct, and is already available as a local variable. This also rem...
