CVE-2024-41009 is an out-of-bounds memory-access vulnerability in the Linux kernel BPF ring-buffer implementation. Ring-buffer producer and consumer positions are logical, monotonically increasing counters over a power-of-two circular data area that is virtually mapped twice contiguously. Insufficient validation of outstanding reservations permits a producer to reserve a second record that overlaps an earlier record through the duplicated mapping. The BPF program can then modify the earlier record's otherwise inaccessible header. When the earlier record is submitted or discarded, commit handling uses the corrupted page-offset field to recover the ring-buffer object, potentially dereferencing an invalid location and crashing the kernel. The fix tracks the oldest pending reservation and rejects a reservation when the span from that record to the newest reservation exceeds the ring-buffer size.
