CVE-2026-90134: Linux

EPSS: 0.2% chance of exploitation in the next 30 days.

In the Linux kernel, the following vulnerability has been resolved: ntfs: fix kmap_local_page() usage in compress Several compressed I/O paths discard the address returned by kmap_local_page() and later access or unmap the page using page_address(). This is invalid for highmem pages, and local mappings must also be unmapped using the address returned by kmap_local_page(). Map each destination page in ntfs_decompress() only while producing the current sub-block. Use memcpy_from_page(), memcpy_to_page(), and memzero_page() for the other page accesses. Remove unnecessary local mappings from ntfs_write_cb(), where pages are accessed through the vmap() mapping.

Affected products

• Linux Linux: from 7.1, before 7.2.6 (fixed in 7.2.6)
