- Details
-
In the Linux kernel, the following vulnerability has been resolved:
srcu: Tighten cleanupsrcustruct() GP checks
Currently, cleanupsrcustruct() checks for a grace period in progress, but it does not check for a grace period that has not yet started but which might start at any time. Such a situation could result in a use-after-free bug, so this commit adds a check for a grace period that is needed but not yet started to cleanupsrcustruct().
