CVE-2026-43261

The CVE-2026-43261 entry concerns the Linux kernel ARM64 arm64: TSV110 Spectre-BHB mitigation. The root cause is Spectre-BHB leakage via branch-prediction side channels on TSV110; mitigation consists of adding the TSV110 MIDR to the software mitigation list in the kernel. Affected component: Linu...

CVE-2026-43261 arm64: Add support for TSV110 Spectre-BHB mitigation

In the Linux kernel, the following vulnerability has been resolved: arm64: Add support for TSV110 Spectre-BHB mitigation The TSV110 processor is vulnerable to the Spectre-BHB Branch History Buffer attack, which can be exploited to leak information through branch prediction side channels. This...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the TSV110 processor’s susceptibility to Spectre-BHB attacks, potentially leading to information...

CVE-2026-31781

In the Linux kernel, the following vulnerability has been resolved: drm/ioc32: stop speculation on the drmcompatioctl path The drm compat ioctl path takes a user controlled pointer, and then dereferences it into a table of function pointers, the signature method of spectre problems. Fix this up b...

CVE-2026-31781

CVE-2026-31781 concerns the Linux kernel drm/ioc32 compat ioctl path, where a user-controlled pointer was used to index a table of function pointers (spectre-like pattern). The issue is mitigated by applying array_index_nospec on the index to the function-pointer list, as described in the fix. Co...

SUSE CVE-2026-31483

In the Linux kernel, the following vulnerability has been resolved: s390/syscalls: Add spectre boundary for syscall dispatch table The s390 syscall number is directly controlled by userspace, but does not have an arrayindexnospec boundary to prevent access past the syscall function pointer tables...

CVE-2026-31483

A flaw was found in the Linux kernel's s390 architecture syscalls. A local attacker, by controlling the syscall number, could potentially access memory beyond the intended syscall function pointer tables. This lack of a boundary check, related to speculative execution Spectre, may lead to...

CVE-2026-31483

CVE-2026-31483 affects the s390 architecture in the Linux kernel. The root cause is a missing array_index_nospec() boundary in the syscall dispatch table, allowing a user-controlled syscall number to exceed the function pointer table and potentially read kernel memory via speculative execution (S...
