CVE-2026-89983

CVE-2026-89983 is a use-after-free vulnerability in the Linux kernel I2C core subsystem. The root cause is a race condition: i2c_del_adapter() frees the adapter's debugfs directory before the adapter device is fully unregistered, while the new_device sysfs attribute remains writable until device_...

CVE-2026-89809

CVE-2026-89809 is a NULL pointer dereference in the Linux kernel's AMD KFD driver (drm/amdkfd). The bug is in the pqm_debugfs_mqds function: a for-loop calling mqd_mgr->debugfs_show_mqd() is incorrectly placed outside the if (pqn->q) block that initializes mqd_mgr. When a process holds a KF...
