CVE-2026-98687

The Linux kernel thunderbolt driver contains a heap out-of-bounds read vulnerability in the tb_xdp_properties_request() function. A malicious peer can set an XDomain length field to 63, leading the driver to treat the data as 48 dwords despite only allocating room for 45. This mismatch causes mem...

CVE-2026-98686

The Linux kernel contains a vulnerability in the smb client component where smb3_zero_range() fails to discard the pagecache for folios straddling the old EOF when extending a file via a zero range. This allows data dirtied past the EOF—potentially through an mmap —to remain in the pagecache and ...

CVE-2026-98685

The Linux kernel contains a vulnerability in the smb client where the cifs_remap_file_range() function fails to correctly discard the pagecache when extending a file via a clone range. Specifically, folios straddling the old EOF (which might contain data dirtied past the EOF via an mmap ) were no...
