CVE-2026-31741

A flaw was found in the Linux kernel's rz-mtu3-cnt counter module. A local user can exploit this by repeatedly writing '0' to the sysfs enable file, which causes the runtime Power Management PM usage count to underflow. This can lead to attempts to access hardware registers with their clocks off,...

CVE-2026-31740

A flaw was found in the Linux kernel's rz-mtu3-cnt counter driver. A race condition exists where multiple sub-drivers can simultaneously attempt to assign their device pointers to a shared channel member. This can result in the counter sub-driver performing power management actions on an unintend...

CVE-2026-31740

CVE-2026-31740 : In the Linux kernel, a race condition can occur in the rz-mtu3-cnt counter driver where the shared rz_mtu3_channel.dev pointer is overwritten by the counter and PWM sub-drivers when assigning device pointers for channels 1 and 2. This can lead the counter sub-driver to perform ru...

CVE-2026-31741

CVE-2026-31741 affects the Linux kernel rz-mtu3-cnt counter module. Repeated writes to the sysfs enable file can underflow/overflow the Runtime PM usage count, causing clocked-off hardware register accesses and potential instability/DoS. The issue is resolved in upstream kernel (v6.6.137) and dis...
