**Name of the Vulnerable Software and Affected Versions** Linux Kernel (affected versions not specified) **Description** The issue is related to the use of memory after it has been freed in the `llcp sock connect()` function. This could potentially allow an attacker to escalate their privileges. The problem is caused by a refcount leak in the `llcp sock connect()` function, leading to a use-after-free condition. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Linux Kernel (affected versions not specified) **Description** The issue is related to the use of memory after it has been freed in the llcp sock bind() function of the NFC protocol in the Linux kernel. This could allow a local attacker to access sensitive data, compromise its integrity, and cause a denial of service. The vulnerability might also lead to privilege escalations. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** A memory leak issue was discovered in the Linux kernel, specifically in the `llcp sock connect()` function related to the NFC protocol. This issue is associated with incorrect memory deallocation before removing the last reference, which could allow a remote attacker to cause a denial of service. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** A flaw in the Linux kernel performance monitoring subsystem was found, related to the use of PERF EVENT IOC SET FILTER. This issue could allow a local user to cause a denial of service by starving system resources. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** A vulnerability was found in the Linux kernel where a non-blocking socket in the `llcp sock connect()` function leads to a leak and eventually causes the system to hang. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
