In the Linux kernel, the following vulnerability has been resolved:

ftrace: Initialize modname and offset in print_rec()

print_rec() leaves 'modname' and 'offset' uninitialized and kallsyms_lookup() only sets them on success. When the lookup fails like when a module is being loaded or unloaded, 'modname' holds a garbage value, passes the 'if (modname)' check, and is dereferenced by seq_printf().

Oops: general protection fault RIP: 0010:string+0x48/0xe0 Call Trace: vsnprintf+0x1f5/0x650 seq_printf+0x8e/0xb0 print_rec+0x6c/0xc0 t_show+0x4c/0x440 seq_read_iter+0x119/0x480

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.

WID-SEC-W-2026-4302 — Linux Kernel: Mehrere Schwachstellen ermöglichen nicht spezifizierten Angriff

Ein Angreifer kann mehrere Schwachstellen im Linux Kernel ausnutzen, um einen nicht näher spezifizierten Angriff durchzuführen, darunter möglicherweise die Auslösung eines Denial-of-Service-Angriffs, die Manipulation oder Offenlegung von Daten, die Ausführung von beliebigem Code, die Erlangung erweiterter Berechtigungen oder die Umgehung von Sicherheitsmaßnahmen.
