CVE-2026-92881

A security vulnerability has been detected in vgmstream. The affected element is the function initvgmstreamawbmemory of the file src/meta/awb.c of the component AWB parser. Such manipulation leads to divide by zero. The attack can be executed remotely. The name of the patch is...

CVE-2026-93182

CVE-2026-93182 is a u32 overflow in the Linux kernel's CFS scheduler (sched/fair), specifically in update_tg_cfs_runnable(). The overflow occurs when se->avg.runnable_avg * divider exceeds the 32-bit range, corrupting the runnable sum and cascading through load-average propagation to produce a...

CVE-2026-90100

CVE-2026-90100 affects the Linux kernel PTP (Precision Time Protocol) netc driver. The root cause is a period truncation in net_timer_enable_perout(): a u64 max_period bound exceeds U32_MAX when integral_period > 0, allowing a period_ns value to pass the range check but be silently truncated t...

EUVD-2026-81961

In the Linux kernel, the following vulnerability has been resolved: ptp: netc: fix period truncation and potential divide-by-zero in PEROUT The maxperiod bound in nettimerenableperout was computed as: maxperiod = u64NETCTMRDEFAULTFIPER + integralperiod; which exceeds U32MAX when integralperiod 0...

CVE-2026-92881

vgmstream contains a divide by zero vulnerability in the AWB parser component, specifically in the function init_vgmstream_awb_memory located in src/meta/awb.c. The flaw can be triggered remotely with user interaction (e.g., processing a crafted AWB file), resulting in a low availability impact w...

CVE-2026-89821

CVE-2026-89821 affects the Linux kernel DRM AMD display subsystem. The function __is_lut_linear() computes each LUT entry as i * MAX_DRM_LUT_VALUE / (size - 1). When called with a single-entry LUT , the divisor becomes zero, triggering a kernel divide error (#DE) . Since a LUT with fewer than two...
