kernel: use-after-free in ucma_leave_multicast in drivers/infiniband/core/ucma.c

A flaw was found in the Linux Kernel in the ucmaleavemulticast function in drivers/infiniband/core/ucma.c which allows access to a certain data structure after freeing it in ucmaprocessjoin. This allows an attacker to cause a use-after-free bug and to induce kernel memory corruption, leading to a...
