  "message": "s390/mm: Fix memory leak in add_marker() when kvrealloc() fails\n\nThe function has a memory leak when kvrealloc() fails.\nThe function directly assigns NULL to the markers pointer, losing the\nreference to the previously allocated memory. This causes kvfree() in\npt_dump_init() to free NULL instead of the leaked memory.\n\nFix by:\n1. Using kvrealloc() uniformly for all allocations\n2. Using a temporary variable to preserve the original pointer until\n   allocation succeeds\n3. Removing the error path that sets markers_cnt\u003d0 to keep\n   consistency between markers and markers_cnt\n\nFound via static analysis and this is similar to commit 42378a9ca553\n(\"bpf, verifier: Fix memory leak in array reallocation for stack state\")\n\nFixes: d0e7915d2ad3 (\"s390/mm/ptdump: Generate address marker array dynamically\")\nCc: stable@vger.kernel.org\nSigned-off-by: Miaoqian Lin \u003clinmq006@gmail.com\u003e\nSigned-off-by: Heiko Carstens \u003chca@linux.ibm.com\u003e\n",
