CVE-2023-52936

Summary

CVE-2023-52936 is a vulnerability affecting the Linux kernel where a memory leak occurs when using debugfs_lookup() in kernel/irq/irqdomain.c. The issue arises when the result of debugfs_lookup() is not followed by a call to dput(). To mitigate this issue, it is recommended to use debugfs_lookup_and_remove() instead, which handles the logic of releasing the memory at once. This vulnerability could potentially lead to a denial of service or other unintended consequences if exploited. The Linux kernel team has released a patch to resolve this issue.
