  "summary": "CVE-2026-99219 is fixed in linux on 1 platform, first by DEBIAN-CVE-2026-99219, released November 3, 2026. It is not reported as exploited. Patch Radar priority: Routine.",
  "title": "ftrace: Initialize modname and offset in print_rec()",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  ftrace: Initialize modname and offset in print_rec()  print_rec() leaves \u0027modname\u0027 and \u0027offset\u0027 uninitialized and kallsyms_lookup() only sets them on success. When the lookup fails like when a module is being loaded or unloaded, \u0027modname\u0027 holds a garbage value, passes the \u0027if (modname)\u0027 check, and is dereferenced by seq_printf().    Oops: general protection fault   RIP: 0010:string\u002B0x48/0xe0   Call Trace:    vsnprintf\u002B0x1f5/0x650    seq_printf\u002B0x8e/0xb0    print_rec\u002B0x6c/0xc0    t_show\u002B0x4c/0x440    seq_read_iter\u002B0x119/0x480  This can be triggered by reading available_filter_functions while a module is being loaded or unloaded.  Initialize both variables so a failed lookup skips the module name.",
