In the Linux kernel, the following vulnerability has been resolved:

tracing: Keep the predicate limit separate from program capacity

predicate_parse() adds two to nr_preds to reserve the terminal TRUE

and FALSE entries. It also uses that increased value as the limit for

parsed predicates. If the initial count is smaller than the number

actually parsed, the program can fill the allocation and subsequent

accesses can go past its end.

Keep nr_preds as the predicate limit and use a separate value for the

allocation size. This leaves space for both terminal entries and a

zeroed entry when parsing stops at the limit. (NVD)

Monitor Linux's web page for any future patch releases.
