Description
A flaw was found in the netfilter: nft_ct component of the Linux kernel. The nft_ct_expect_obj_eval() function allocates an expectation but fails to release its local reference. This oversight leads to a resource leak, which could potentially allow a local attacker to cause a denial of service by exhausting system resources.
