CVE-2026-0988: Red Hat Enterprise Linux 10

Low severity, CVSS 3.7. EPSS: 0.4% chance of exploitation in the next 30 days.

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).
