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-2026-74545

CVE-2026-74545 is a Linux kernel issue where rtase_start_xmit() can double-free an skb on DMA map failure after fragments are mapped. The fix changes control flow to return immediately after clearing fragments when the skb owns frags; the no-frag path still frees the head skb once. Public advisor...
