USN-8596-1: Linux kernel (NVIDIA) 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...

USN-8566-1 linux, linux-gcp, linux-gke, linux-realtime vulnerabilities

It was discovered that some AMD Zen 2 processors did not properly isolate shared resources in the operation cache. A local attacker could possibly use this issue to corrupt instructions executed at a higher privilege level, resulting in privilege escalation. CVE-2025-54518 Several security issues...

CVE-2026-64134 ALSA: pcm: Don't setup bogus iov_iter for silencing

In the Linux kernel, the following vulnerability has been resolved: ALSA: pcm: Don't setup bogus ioviter for silencing At transition to the ioviter for PCM data transfer, we blindly applied the ioviter setup also for silencing i.e. data = NULL, and it leads to a calculation of bogus ioviter...

CVE-2026-64134

The CVE-2026-64134 entry concerns the Linux kernel ALSA PCM path. The vulnerability arises during transition to iov_iter for PCM data transfer, where iov_iter was also configured for silencing (data = NULL), leading to a bogus iov_iter calculation and a NULL dereference on some architectures, not...
