CVE-2025-22074

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2025-22074
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.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ksmbd: se corrige la discrepancia entre r_count decrement y decrement. r_count solo aumenta cuando hay una espera de interrupción de oplock, por lo que r_count inc/decrement no se empareja. Esto puede provocar que r_count sea negativo, lo que puede provocar un problema donde el subproceso ksmbd no termina.
