CVE-2026-99063

The Linux kernel contains a vulnerability in the dm ioctl handling where the get_result_buffer() function fails to verify the buffer size relative to the struct dm_ioctl trailing padding. This allows data_start to point seven bytes past the end of the buffer, leading to a slab-out-of-bounds read ...
