CVE-2024-47723 HIGH

Published: 2024-10-21 | Last Modified: 2026-08-04 | Status: Modified

Description

In the Linux kernel, the following vulnerability has been resolved: jfs: fix out-of-bounds in dbNextAG() and diAlloc() In dbNextAG() , there is no check for the case where bmp->db_numag is greater or same than MAXAG due to a polluted image, which causes an out-of-bounds. Therefore, a bounds check should be added in dbMount(). And in dbNextAG(), a check for the case where agpref is greater than bmp->db_numag should be added, so an out-of-bounds exception should be prevented. Additionally, a check for the case where agno is greater or same than MAXAG should be added in diAlloc() to prevent out-of-bounds.

Additional Descriptions (1)

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: jfs: corregir fuera de los límites en dbNextAG() y diAlloc() En dbNextAG(), no hay ninguna comprobación para el caso en el que bmp->db_numag es mayor o igual que MAXAG debido a una imagen contaminada, lo que provoca un out-of-bounds. Por lo tanto, se debe agregar una comprobación de los límites en dbMount(). Y en dbNextAG(), se debe agregar una comprobación para el caso en el que agpref es mayor que bmp->db_numag, por lo que se debe evitar una excepción fuera de los límites. Además, se debe agregar una comprobación para el caso en el que agno es mayor o igual que MAXAG en diAlloc() para prevenir out-of-bounds.
