Description

A flaw was found in the Linux kernel. Specifically, a bug in the `map_direct_value_addr()` function, which is part of the Berkeley Packet Filter (BPF) instruction array map, leads to incorrect address calculations when dealing with non-zero offsets. This issue could result in the kernel accessing unintended memory locations. While the direct security impact is not explicitly detailed, such memory access issues can potentially lead to system instability or information exposure.
