CVE-2026-64269

The CVE-2026-64269 issue affects the Linux kernel’s RDMA path (RDMA/rtrs-srv) where rdma_write_sg() uses desc[0].len from the wire descriptor to determine the RDMA_WRITE length. The length could exceed the bound of the mapped chunk because it wasn’t checked against max_chunk_size, enabling a peer...

CVE-2026-64267

CVE-2026-64267 affects the Linux kernel’s FUSE (Filesystem in Userspace) path. The issue is an integer overflow in handling FUSE_NOTIFY_PRUNE messages on 32-bit architectures, where the product of outarg.count and sizeof(u64) can wrap during payload length validation, potentially causing the kern...

CVE-2026-64257

CVE-2026-64257 affects the Linux kernel SMB2 client logic. The issue arose from overlap handling in __smb2_calc_size(), where clearing data_length could cause an invalid SMB2 response to appear as if it has no data area, allowing an unintended length-exemption path. The fix tracks data area overl...
