Descriptions
In the Linux kernel, the following vulnerability has been resolved:
gfs2: Fix kernel NULL pointer dereference in gfs2_rgrp_dump
Syzkaller has reported a NULL pointer dereference when accessing
rgd->rd_rgl in gfs2_rgrp_dump(). This can happen when creating
rgd->rd_gl fails in read_rindex_entry(). Add a NULL pointer check in
gfs2_rgrp_dump() to prevent that.
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: gfs2: Se corrigió la desreferencia del puntero NULL del kernel en gfs2_rgrp_dump Syzkaller ha informado una desreferencia del puntero NULL al acceder a rgd->rd_rgl en gfs2_rgrp_dump(). Esto puede suceder cuando la creación de rgd->rd_gl falla en read_rindex_entry(). Agregue una verificación de puntero NULL en gfs2_rgrp_dump() para evitarlo.
A NULL pointer dereference flaw was found in the Linux kernel when accessing the rgd->rd_rgl in the gfs2_rgrp_dump() function. This issue may lead to a crash.
