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