  "details": "In the Linux kernel, the following vulnerability has been resolved:  xfrm: fix refcount leak in xfrm_migrate_policy_find  syzkaller reported a memory leak in xfrm_policy_alloc:    BUG: memory leak   unreferenced object 0xffff888114d79000 (size 1024):     comm \"syz.1.17\", pid 931     ...     xfrm_policy_alloc+0xb3/0x4b0 net/xfrm/xfrm_policy.c:432  The root cause is a double call to xfrm_pol_hold_rcu() in xfrm_migrate_policy_find(). The lookup function already returns a policy with held reference, making the second call redundant.  Remove the redundant xfrm_pol_hold_rcu() call to fix the refcount imbalance and prevent the memory leak.  Found by Linux Verification Center (linuxtesting.org) with Syzkaller.",
