Summary
In the Linux kernel, the following vulnerability has been resolved: misc: fastrpc: fix memory corruption on open The probe session-duplication overflow check incremented the session count also when there were no more available sessions so that memory beyond the fixed-size slab-allocated session array could be corrupted in fastrpc_session_alloc() on open().
