CVE-2026-90134

In the Linux kernel, the following vulnerability has been resolved: ntfs: fix kmaplocalpage usage in compress Several compressed I/O paths discard the address returned by kmaplocalpage and later access or unmap the page using pageaddress. This is invalid for highmem pages, and local mappings must...

CVE-2026-92501

CVE-2026-92501 is a race condition in the Linux kernel's ext4 filesystem, affecting the direct I/O (DIO) to buffered write fallback path in ext4_dio_write_iter(). On no-extent inodes (e.g., ext3), DIO writes to holes cause a fallback to buffered I/O. An unprotected window exists between ext4_buff...
