kernel: Arm Processors: Privilege escalation or information disclosure via writes to higher exception level resources

A flaw was found in the Linux kernel on ARM processors. A race condition in Translation Lookaside Buffer Invalidation TLBI operations during memory permission changes allows a local attacker to write to memory resources owned by higher privilege levels. This could allow an unprivileged local...

CVE-2026-64286

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM for arm64 architecture. The flushhypvcpu function, responsible for copying the host virtual CPU vCPU context, does not properly clear a specific internal pointer hyprunningvcpu. This oversight allows a host to provide a value...

CVE-2026-64282

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine for arm64 architectures. A race condition between the kvmtranslatevncr function and an MMU Memory Management Unit notifier can lead to a Page Frame Number PFN leak. This occurs because an early return in kvmtranslatevncr fail...

CVE-2026-64287

A flaw was found in the Kernel-based Virtual Machine KVM component of the Linux kernel on ARM64 systems. A highly privileged local attacker could exploit a vulnerability where the system fails to properly restrict memory access during a specific virtual machine operation. This could allow the...

CVE-2026-64288

A flaw was found in the kernel's Kernel-based Virtual Machine KVM component for ARM64 architectures. A race condition can occur during the invalidation of the virtual Nested Translation Cache VNCR pseudo-TLB when a virtual CPU vcpu is being brought online or offline. This can lead to a null point...

USN-8623-1: Linux kernel (NVIDIA) vulnerabilities

Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - ARM64 architecture; - Arm Firmware Framework for ARMv8-AFFA; CVE-2026-53354, CVE-2026-64520...

USN-8623-1 linux-nvidia-6.17 vulnerabilities

CVE-2026-64520

A flaw was found in the Linux kernel's ARM Firmware Framework for ARM FFA. The PARTITIONINFOGETREGS function, which handles copying partition descriptors, did not adequately validate the indices provided by the firmware. This oversight could allow the system to process inconsistent data, resultin...

USN-8620-2 linux-azure-fips vulnerabilities

Maxim Suhanov discovered that the NTFS file system implementation in the Linux kernel did not properly validate file name length in certain situations, leading to an out-of-bounds read. An attacker could use this to construct a malicious NTFS image that, when mounted and operated on, could expose...

grant-table: version change racing with other operations

ISSUE DESCRIPTION With the introduction of Grant Table v2 came the requirement to be able to switch between versions. Switching from v1 to v2 reduces the number of valid grant references, as a bigger shared entry structure is then needed while the shared table doesn't change size. Switching from ...

USN-8595-3 linux-aws-6.8, linux-aws-fips 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-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...

USN-8618-1: Linux kernel 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...
