Description

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