"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nring-buffer: Fix possible dereference of uninitialized pointer\n\nThere is a pointer head_page in rb_meta_validate_events() which is not\ninitialized at the beginning of a function. This pointer can be dereferenced\nif there is a failure during reader page validation. In this case the control\nis passed to \"invalid\" label where the pointer is dereferenced in a loop.\n\nTo fix the issue initialize orig_head and head_page before calling\nrb_validate_buffer.\n\nFound by Linux Verification Center (linuxtesting.org) with SVACE."
