CVE-2025-40062
crypto: hisilicon/qm - set NULL to qm->debug.qm_diff_regs
概要
crypto: hisilicon/qm - set NULL to qm->debug.qm_diff_regs
原文の説明
取得元が公開している説明をそのまま載せています (多くは英語)。
In the Linux kernel, the following vulnerability has been resolved:
crypto: hisilicon/qm - set NULL to qm->debug.qm_diff_regs
When the initialization of qm->debug.acc_diff_reg fails,
the probe process does not exit. However, after qm->debug.qm_diff_regs is
freed, it is not set to NULL. This can lead to a double free when the
remove process attempts to free it again. Therefore, qm->debug.qm_diff_regs
should be set to NULL after it is freed.
