CVE-2026-64529

In the Linux kernel, the following vulnerability has been resolved: crypto: qat - remove unused character device and IOCTLs The QAT driver exposes a character device qatadfctl with IOCTLs for device configuration, start, stop, status query and enumeration. These IOCTLs are not part of any public...

CVE-2026-64385

In the Linux kernel, the following vulnerability has been resolved: smb: client: fix double-free in SMB2ioctl replay A response-bearing attempt can return a replayable error and free its response buffer. If SMB2ioctlinit fails before the next send, cleanup retains the previous buffer type and fre...
