CVE-2026-89505

CVE-2026-89505 is a vulnerability in the Linux kernel RDMA/uverbs subsystem. In the legacy write() path, the uverbs_attr_bundle passed to provider code does not contain an ioctl method element. If malformed provider input causes the common uverbs validation code to emit an error message, uverbs_g...

CVE-2026-89504

CVE-2026-89504 is a use-after-free (dangling pointer) vulnerability in the Linux kernel's regulator subsystem , specifically in the as3722 driver. In as3722_get_regulator_dt_data(), a device tree node reference acquired via of_get_child_by_name() is prematurely released by an immediate of_node_pu...
