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...

USN-8620-2: Linux kernel (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.

CVE-2026-64369

A flaw was found in the Linux kernel, specifically within the s390 architecture. When the system attempts to read unaligned data that spans across memory pages, it can trigger exceptions. For memory pages designated for secure execution by the Ultravisor, the exception handling mechanism does not...

CVE-2026-42493 x86 shadow paging is deprecated

Addressing certain issues, in particular related to operations which may take excessively long and therefore would need preemption, has turned out overly costly. Since alternatives HVM/PVH: HAP, PV: shim are commonly available, the decision was to deprecate the functionality, while still retainin...

CVE-2026-42493

XEN CVE-2026-42493 involves x86 shadow paging. The XSA advisory states the feature is deprecated due to costly preemption handling, with alternatives (HVM/PVH: HAP, PV: shim) available, though retained for security-risk use. Affects all x86 Xen builds with SHADOW_PAGING=y; unprivileged guests may...

CVE-2026-64248

A flaw was found in the Linux kernel, specifically affecting systems using the MIPS architecture. During the shutdown process of a CPU, the kernel's internal mechanism responsible for managing concurrent data access Read-Copy Update or RCU is not properly informed that the CPU is no longer active...
