CVE-2026-43379

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ksmbd: fix use-after-free in smb_lazy_parent_lease_break_close()<br /> <br /> opinfo pointer obtained via rcu_dereference(fp-&gt;f_opinfo) is being<br /> accessed after rcu_read_unlock() has been called. This creates a<br /> race condition where the memory could be freed by a concurrent<br /> writer between the unlock and the subsequent pointer dereferences<br /> (opinfo-&gt;is_lease, etc.), leading to a use-after-free.
