CVE-2026-74504

In the Linux kernel, the following vulnerability has been resolved: ALSA: seq: Fix division by zero in initializetimer A userspace-driven ALSA timer SNDUTIMER lets an unprivileged user set the backing sndtimer's hardware resolution to an arbitrary 64-bit value via SNDRVTIMERIOCTLCREATE...

CVE-2026-74546

CVE-2026-74546 affects the Linux kernel hwmon adt7470 driver. A TOCTOU race can occur if fan data becomes 0 between the FAN_DATA_VALID() check and the FAN_PERIOD_TO_RPM() conversion, causing a divide-by-zero crash. The issue is mitigated by reading fan data once to prevent a concurrent update fro...

CVE-2026-74504

Summary (CVE-2026-74504): The Linux kernel ALSA sequencing timer (SND_UTIMER) can be driven by an unprivileged user to set arbitrary 64‑bit hardware resolution for snd_timer via SNDRV_TIMER_IOCTL_CREATE. When bound to a sequencer queue, initialize_timer() computes tmr->ticks = 1_000_000_000 / ...

EUVD-2026-59756

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix divide-by-zero in calculatemcachesetting on zero viewport If a plane reaches calculatemcachesetting with a zero-area viewport, calculatemcachesetting exits early with nummcaches == 0 and mvmpgwidth/height == ...

CVE-2026-74449

In CVE-2026-74449, the Linux kernel drm/amd/display pipeline has a divide-by-zero bug in calculate_mcache_setting when a zero-area viewport is processed. The function can exit with num_mcaches == 0 and mvmpg_width/height == 0, causing a divide-by-zero panic and potential underflow. The fix change...

CVE-2026-72394

The CVE pertains to the Linux kernel hwmon subsystem, specifically the aspeed-g6-pwm-tach driver. The aspeed_tach_val_to_rpm() function computes fan RPM from the tachometer value without guarding against tach value 0. If tach_div becomes 0, a subsequent do_div() division by zero triggers a kernel...
