CVE-2026-89616

A flaw was found in the Linux kernel's NTFS3 filesystem driver. When decompressing LZNT data, the ni_read_frame() function may not fully zero out memory after a partial decompression. This can lead to the disclosure of previously used kernel memory pages to a local attacker who reads a specially crafted compressed file. Successful exploitation could allow an attacker to obtain sensitive kernel pointers, potentially bypassing Kernel Address Space Layout Randomization (KASLR) and aiding further attacks.
