DEBIAN-CVE-2026-64468

In the Linux kernel, the following vulnerability has been resolved: binder: fix UAF in binderfreetransaction In binderfreetransaction, the t-toproc is read under the t-lock. However, once the t-lock is dropped, the toproc can die in parallel. This leads to a use-after-free error when we attempt t...
