CVE-2026-64328

A flaw was found in the Linux kernel's USB gadget subsystem. Specifically, a DMA Direct Memory Access fence leak exists in the ffs module's ffsdmabuftransfer function. This issue causes ffsdmafence objects to be allocated without their initial reference being properly released. Repeated...

USN-8574-3: Linux kernel vulnerabilities

It was discovered that some AMD processors did not properly clear data in the floating point divider unit during speculative execution. A local attacker could use this to expose sensitive information. CVE-2025-54505 It was discovered that some AMD Zen 2 processors did not properly isolate shared...
