  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\nnet/x25: Fix overflow when accumulating packets\nAdd a check to ensure that `x25_sock.fraglen` does not overflow.\nThe `fraglen` also needs to be resetted when purging `fragment_queue` in\n`x25_clear_queues()`.", "A flaw was found in the Linux kernel's X.25 network protocol implementation (net/x25). An attacker could potentially trigger an integer overflow in the `x25_sock.fraglen` variable when accumulating packets. This oversight, combined with the `fraglen` not being properly reset, may lead to system instability or a denial of service." ],
