  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nftrace: Initialize modname and offset in print_rec()\n\nprint_rec() leaves 'modname' and 'offset' uninitialized and\nkallsyms_lookup() only sets them on success. When the lookup fails like\nwhen a module is being loaded or unloaded, 'modname' holds a garbage\nvalue, passes the 'if (modname)' check, and is dereferenced by\nseq_printf().\n\n  Oops: general protection fault\n  RIP: 0010:string+0x48/0xe0\n  Call Trace:\n   vsnprintf+0x1f5/0x650\n   seq_printf+0x8e/0xb0\n   print_rec+0x6c/0xc0\n   t_show+0x4c/0x440\n   seq_read_iter+0x119/0x480\n\nThis can be triggered by reading available_filter_functions while a\nmodule is being loaded or unloaded.\n\nInitialize both variables so a failed lookup skips the module name.",
