CVE-2026-74547

A flaw was found in the Linux kernel's hwmon adt7470 component. A local user can exploit this by configuring the 'autoupdateinterval' to zero via sysfs while 'numtempsensors' is also set to zero. This combination forces the background thread into an unbounded busy-loop, consuming CPU resources an...

CVE-2026-74547

The CVE-2026-74547 entry concerns the Linux kernel hwmon driver for adt7470. When auto_update_interval is set to 0, the background update thread can schedule a zero-delay wakeup and, if num_temp_sensors is 0, msleep_interruptible() also becomes 0, causing a tight, unbounded busy-loop that hogs CP...

CVE-2026-11352 QUIC zero-length UDP datagrams busy-loop

An issue in curl’s QUIC UDP receive function allows a malicious HTTP/3 server to trigger a remote denial of service against a curl or libcurl client. Because the helper function discards zero-length UDP datagrams before counting them toward the per-call packet budget, a connected QUIC peer can...
