      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ntest_kprobes: clear kprobes between test runs\n\nRunning the kprobes sanity tests twice makes all tests fail and\neventually crashes the kernel.\n\n[root@martin-riscv-1 ~]# echo 1 > /sys/kernel/debug/kunit/kprobes_test/run\n...\n   # Totals: pass:5 fail:0 skip:0 total:5\n   ok 1 kprobes_test\n[root@martin-riscv-1 ~]# echo 1 > /sys/kernel/debug/kunit/kprobes_test/run\n...\n  # test_kprobe: EXPECTATION FAILED at lib/tests/test_kprobes.c:64\n  Expected 0 == register_kprobe(&kp), but\n      register_kprobe(&kp) == -22 (0xffffffffffffffea)\n...\n  Unable to handle kernel paging request ...\n\nThe testsuite defines several kprobes and kretprobes as static variables\nthat are preserved across test runs.\n\nAfter register_kprobe and unregister_kprobe, a kprobe contains some\nleftover data that must be cleared before the kprobe can be registered\nagain. The tests are setting symbol_name to define the probe location.\nAddress and flags must be cleared.\n\nThe existing code clears some of the probes between subsequent tests, but\nnot between two test runs. The leftover data from a previous test run\nmakes the registrations fail in the next run.\n\nMove the cleanups for all kprobes into kprobes_test_init, this function\nis called before each single test (including the first test of a test\nrun).",
