Lin Horse

**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue is related to a use-after-free flaw in the sco sock sendmsg() function of the Linux kernel's HCI subsystem. This flaw can be triggered by a privileged local user through specific system calls, such as ioct UFFDIO REGISTER, which can cause a race condition with the sco conn del() and sco sock sendmsg() calls. This can lead to a controllable faulting memory page. The exploitation of this issue may result in a system crash or allow an attacker to escalate their privileges on the system. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
