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...
