CVE-2025-38547

Kernel crash via unterminated ADC channel map

Published Aug 16, 2025 · Updated Aug 5, 2026

Out-of-bounds read in Linux kernel 6.12 through 6.15.7 allows local users to crash AXP717-equipped systems during ADC probing. The axp20x_probe path passes an unterminated axp717_maps array to IIO map registration, which walks beyond the array and installs entries derived from adjacent kernel data. Reaching the flaw requires an AXP717-equipped board and driver probing; later string comparisons against the bogus entries can trigger an oops or panic.
