https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=263396 Bug ID: 263396 Summary: Fix a possible NULL pointer dereference bug in ocs_hw_setup() Product: Base System Version: Unspecified Hardware: Any OS: Any Status: New Severity: Affects Many People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: zhou1615@umn.edu Created attachment 233305 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=233305&action=edit A possible fix for this bug The function ocs_hw_qtop_parse() could return NULL on malloc failure. However the caller function ocs_hw_setup() of ocs_hw_qtop_parse() uses the return value without check, which could lead to NULL pointer dereference. Fix this by adding a NULL check. this patch is a possible fix. -- You are receiving this mail because: You are the assignee for the bug.
