CVE-2025-37817 Details
Description
In the Linux kernel, the following vulnerability has been resolved: mcb: fix a double free bug in chameleon_parse_gdd() In chameleon_parse_gdd(), if mcb_device_register() fails, 'mdev' would be released in mcb_device_register() via put_device(). Thus, goto 'err' label and free 'mdev' again causes a double free. Just return if mcb_device_register() fails.
A double free vulnerability has been identified in the Linux kernel within the Chameleon device driver. The issue arises in the function 'chameleon_parse_gdd()', where the device is released twice if 'mcb_device_register()' fails. This flaw creates a double free condition, which can lead to memory corruption.
