- [none]
- Details
-
In the Linux kernel before 5.3.11, sound/core/timer.c has a use-after-free caused by erroneous code refactoring, aka CID-e7af6307a8a5. This is related to sndtimeropen and sndtimerclose_locked. The timeri variable was originally intended to be for a newly created timer instance, but was used for a different purpose after refactoring.
