CVE-2026-0988
LOW3.7EPSS 0.03%glib2.0 - security update
Published: 1/21/2026Modified: 5/16/2026
Description
A flaw was found in glib. Missing validation of offset and count parameters in the g_buffered_input_stream_peek() function can lead to an integer overflow during length calculation. When specially crafted values are provided, this overflow results in an incorrect size being passed to memcpy(), triggering a buffer overflow. This can cause application crashes, leading to a Denial of Service (DoS).
