CVE-2025-37839

In the Linux kernel, the following vulnerability has been resolved: jbd2: remove wrong sb->s_sequence check Journal emptiness is not determined by sb->s_sequence == 0 but rather by sb->s_start == 0 (which is set a few lines above). Furthermore 0 is a valid transaction ID so the check can spuriously trigger. Remove the invalid WARN_ON.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: jbd2: eliminar la comprobación incorrecta de sb->s_sequence. El vacío del diario no se determina por sb->s_sequence == 0, sino por sb->s_start == 0 (que se establece unas líneas más arriba). Además, 0 es un ID de transacción válido, por lo que la comprobación puede activarse falsamente. Eliminar el WARN_ON no válido.
