CVE-2026-43097

A flaw was found in the Linux kernel's PCI Hyper-V driver. During error handling, a specific resource identifier can be inadvertently freed twice. This double free vulnerability can lead to memory corruption, potentially causing system instability and a Denial of Service DoS...

CVE-2026-43106

A flaw was found in the Linux kernel's cachefiles module, which manages cached files. This vulnerability stems from an error in how the system counts references to certain file system objects, specifically within the cachefilescull function. When a reference is lost, it can lead to system...

CVE-2026-43274

A flaw was found in the Linux kernel's mailbox subsystem, specifically within the mchp-ipc-sbi component. This vulnerability involves an out-of-bounds access in the mchpipcgetclusteraggrirq function. The clustercfg array, which holds per-CPU configuration structures, was incorrectly indexed using...

CVE-2025-71273

A flaw was found in the Linux kernel's rtw88 Wi-Fi driver. This vulnerability is caused by a memory leak within the rtwregisterhw function, where memory allocated for supported bands is not properly released during error conditions. This could allow a local attacker to exhaust system memory,...
