In the Linux kernel, the following vulnerability has been resolved: binder:
check offset alignment in binder_get_object() Commit 6d98eb95b450 (“binder:
avoid potential data leakage when copying txn”) introduced changes to how
binder objects are copied. In doing so, it unintentionally removed an
offset alignment check done through calls to
binder_alloc_copy_from_buffer() -> check_buffer(). These calls were
replaced in binder_get_object() with copy_from_user(), so now an explicit
offset alignment check is needed here. This avoids later complications when
unwinding the objects gets harder. It is worth noting this check existed
prior to commit 7a67a39320df (“binder: add function to copy binder object
from buffer”), likely removed due to redundancy at the time.
