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 smb: client: reject overlapping data areas in SMB2 responses

In the Linux kernel, the following vulnerability has been resolved: smb: client: reject overlapping data areas in SMB2 responses Commit 53b7c271f06b "smb: client: restrict implied bcc0 exemption to responses without data area" restricted the implied bcc0 length exception to responses without a da...

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...
