Summary	(en) In the Linux kernel, the following vulnerability has been resolved: samples/bpf: syscall_tp_user: Fix array out-of-bound access Commit 06744f24696e ("samples/bpf: Add openat2() enter/exit tracepoint to syscall_tp sample") added two more eBPF programs to support the openat2() syscall. However, it did not increase the size of the array that holds the corresponding bpf_links. This leads to an out-of-bound access on that array in the bpf_object__for_each_program loop and could corrupt other variables on the stack. On our testing QEMU, it corrupts the map1_fds array and causes the sample to fail: # ./syscall_tp prog #0: map ids 4 5 verify map:4 val: 5 map_lookup failed: Bad file descriptor Dynamically allocate the array based on the number of programs reported by libbpf to prevent similar inconsistencies in the future	(en) Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.
