Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
crypto: hisilicon/qm - set NULL to qm->debug.qm_diff_regs<br />
<br />
When the initialization of qm->debug.acc_diff_reg fails,<br />
the probe process does not exit. However, after qm->debug.qm_diff_regs is<br />
freed, it is not set to NULL. This can lead to a double free when the<br />
remove process attempts to free it again. Therefore, qm->debug.qm_diff_regs<br />
should be set to NULL after it is freed.
