CVE-2025-40062 crypto: hisilicon/qm - set NULL to qm->debug.qm_diff_regs

In the Linux kernel, the following vulnerability has been resolved: crypto: hisilicon/qm - set NULL to qm-debug.qmdiffregs When the initialization of qm-debug.accdiffreg fails, the probe process does not exit. However, after qm-debug.qmdiffregs is freed, it is not set to NULL. This can lead to a...

CVE-2025-40055

CVE-2025-40055 affects the Linux kernel OCFS2, describing a double-free in the path handling user_cluster_connect(). The root cause is that user_cluster_disconnect() frees the same memory as conn->cc_private (the lc object) and the error handling frees lc again, leading to a double-free. The d...
