kernel: KVM: x86: Don't (re)check L1 intercepts when completing userspace I/O

A flaw was found in the Kernel-based Virtual Machine KVM for x86. This vulnerability occurs when KVM incorrectly re-checks Level 1 L1 intercepts during the completion of userspace I/O emulation for a Level 2 L2 instruction. If the L1 or host userspace modifies I/O interception settings during thi...

UBUNTU-CVE-2022-4994

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: wean fast IN from emulatorpioin Use emulatorpioin directly for fast PIO instead of bouncing through emulatorpioin now that emulatorpioin fills "val" when handling in-kernel PIO. vcpu-arch.pio.count is guaranteed to be...

CVE-2026-64391

A flaw was found in ksmbd, the in-kernel Server Message Block SMB daemon. This vulnerability allows a remote attacker to bypass security restrictions by incorrectly handling credentials for Alternate Data Streams ADS input/output I/O operations. Instead of using the credentials established when t...

RHEL 8 : kernel (RHSA-2026:47869)

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:47869 advisory. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fixes: kernel: KVM: x86: Don't recheck L1...

CVE-2026-62430

Accesses to the CMOS memory contents are done using an indirect IO port pair. Therefore Xen needs to cache the guest chosen index, and one of the usages of the index didn't take the necessary locking to avoid concurrent changes. As a result, a guest could change the index after it being checked,...

CVE-2026-64529

Summary: CVE-2026-64529 exists in the Linux kernel and concerns the QAT driver. The vulnerability stems from a previously exposed character device (qat_adf_ctl) with IOCTLs used for device configuration, start/stop, status, and enumeration that were not part of public user-space API headers and h...

CVE-2026-64498

The CVE-2026-64498 issue affects the Linux kernel IIO subsystem (iio: buffer: hw-consumer). The root cause was a lifetime change for scan_mask: it moved to a separate bitmap allocation (buffer.scan_mask) but iio_hw_buf_release() remained unchanged, risking improper cleanup. The fix ensures the sc...
