CVE-2023-54102

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> scsi: lpfc: Prevent lpfc_debugfs_lockstat_write() buffer overflow<br /> <br /> A static code analysis tool flagged the possibility of buffer overflow when<br /> using copy_from_user() for a debugfs entry.<br /> <br /> Currently, it is possible that copy_from_user() copies more bytes than what<br /> would fit in the mybuf char array. Add a min() restriction check between<br /> sizeof(mybuf) - 1 and nbytes passed from the userspace buffer to protect<br /> against buffer overflow.
