Linux Kernel Vulnerability Affecting BPF Program Execution

CVE-2023-53290

What is CVE-2023-53290?

The Linux kernel has a vulnerability in the BPF (Berkeley Packet Filter) program execution path, specifically related to the management of file output streams. The issue arises from a fout resource being opened without being properly closed, leading to potential resource leakage. This could affect system performance and stability when handling BPF programs, as the incomplete closing of fout leaves the resource open until it goes out of scope. Addressing this issue is essential for maintaining resource efficiency and preventing unintended behavior in BPF applications.
