CVE-2023-53139

Service interruption via unchecked allocation failure

Published May 2, 2025 · Updated May 11, 2026

Out-of-bounds write in Linux kernel 4.4 through 6.3-rc1 allows local users to interrupt service during FDP NFC device initialization. fdp_nci_i2c_read_device_properties passes a null fw_vsc_cfg buffer to device_property_read_u8_array when devm_kmalloc_array fails. The FDP NFC property must be present and the allocation must fail; the resulting kernel-memory write can crash or destabilize the system.
