**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue is related to a deadlock flaw in the Linux kernel's BPF subsystem, which can be exploited by a local user to potentially crash the system. Additionally, there is a problem with the sock hash delete elem() function in the net/core/sock map.c module, associated with incorrect serialization of the htab->buckets[i].lock resource, allowing an 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** The issue is related to an out-of-bounds memory read flaw in the Linux kernel's BPF subsystem. This occurs when a user calls the `bpf tail call()` function with a key larger than the `max entries` of the map. The flaw allows a local user to gain unauthorized access to data. It is also described as a buffer copying issue without input size validation, which can be exploited to gain unauthorized access to data. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
