Overview Affected versions of this package are vulnerable to NULL Pointer Dereference and out-of-bounds read in the native XXHash implementations reached through XXHashFactory.nativeInstance, where SafeUtils.checkRange skips all array validation when len == 0 and lets invalid references or ranges...

CVE-2026-64234

The CVE-2026-64234 entry concerns the Linux kernel tty/serial driver pch_uart. The root cause is a missing check of the return value from dma_alloc_coherent(), which could yield a NULL pointer, triggering a crash in dma_handle_rx(). The fix adds a guard for dma_alloc_coherent() failure and ensure...
