Description

ovl: relax WARN_ON in ovl_verify_area()

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

ovl: relax WARN_ON in ovl_verify_area()

syzbot hit an assertion in copy up data loop which looks like it is

the result of a lower file whose size is being changed underneath

overlayfs.

This type of use case is documented to cause undefined behavior, so

returning EIO error for the copy up makes sense, but it should not be

causing a WARN_ON assertion.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity none, availability high.
