Description

An issue was discovered in the Linux kernel before 5.0.10. There is a use-after-free in the sound subsystem because card disconnection causes certain data structures to be deleted too early. This is related to sound/core/init.c and sound/core/info.c. A vulnerability was found in the Linux kernel’s core sound driver code. A use-after-free in a race condition between disconnection events could allow a local attacker who can trigger disconnection events (remove or add hardware) to crash the system, corrupt memory, or escalate privileges.
