  3. CVE-2024-38576
In the Linux kernel, the following vulnerability has been resolved: rcu: Fix buffer overflow in print_cpu_stall_info() The rcuc-starvation output from print_cpu_stall_info() might overflow the buffer if there is a huge difference in jiffies difference. The situation might seem improbable, but computers sometimes get very confused about time, which can result in full-sized integers, and, in this case, buffer overflow. Also, the unsigned jiffies difference is printed using %ld, which is normally for signed integers. This is intentional for debugging purposes, but it is not obvious from the code. This commit therefore changes sprintf() to snprintf() and adds a clarifying comment about intention of %ld format. Found by Linux Verification Center (linuxtesting.org) with SVACE.

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: rcu: corrige el desbordamiento del búfer en print_cpu_stall_info() La salida rcuc-starvation de print_cpu_stall_info() podría desbordar el búfer si hay una gran diferencia en santiamén. La situación puede parecer improbable, pero las computadoras a veces se confunden mucho con el tiempo, lo que puede resultar en números enteros de tamaño completo y, en este caso, en un desbordamiento del búfer. Además, la diferencia de santiamén sin signo se imprime usando %ld, que normalmente es para enteros con signo. Esto es intencional con fines de depuración, pero no es obvio en el código. Por lo tanto, esta confirmación cambia sprintf() a snprintf() y agrega un comentario aclaratorio sobre la intención del formato %ld. Encontrado por el Centro de verificación de Linux (linuxtesting.org) con SVACE.
