CVE-2025-22074

MediumCVSS 5.5/10Last modified Oct 30, 2026

Description

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

ksmbd: fix r_count dec/increment mismatch

r_count is only increased when there is an oplock break wait, so r_count inc/decrement are not paired. This can cause r_count to become negative, which can lead to a problem where the ksmbd thread does not terminate.
