CVE-2024-38780 MEDIUM

Published: 2024-06-21 | Last Modified: 2026-05-12 | Status: Modified

Description

In the Linux kernel, the following vulnerability has been resolved: dma-buf/sw-sync: don't enable IRQ from sync_print_obj() Since commit a6aa8fca4d79 ("dma-buf/sw-sync: Reduce irqsave/irqrestore from known context") by error replaced spin_unlock_irqrestore() with spin_unlock_irq() for both sync_debugfs_show() and sync_print_obj() despite sync_print_obj() is called from sync_debugfs_show(), lockdep complains inconsistent lock state warning. Use plain spin_{lock,unlock}() for sync_print_obj(), for sync_debugfs_show() is already using spin_{lock,unlock}_irq().

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: dma-buf/sw-sync: no habilitar IRQ desde sync_print_obj() Desde el commit a6aa8fca4d79 ("dma-buf/sw-sync: reducir irqsave/irqrestore desde el contexto conocido" ) por error reemplazó spin_unlock_irqrestore() con spin_unlock_irq() tanto para sync_debugfs_show() como para sync_print_obj() a pesar de que sync_print_obj() se llama desde sync_debugfs_show(), lockdep se queja de una advertencia de estado de bloqueo inconsistente. Utilice spin_{lock,unlock}() simple para sync_print_obj(), ya que sync_debugfs_show() ya está usando spin_{lock,unlock}_irq().
