[SECURITY] Fedora 43 Update: kernel-headers-6.17.0-0.rc6.49.fc43

Kernel-headers includes the C header files that specify the interface between the Linux kernel and userspace libraries and programs. The header files define structures and constants that are needed for building most standard programs and are also needed for rebuilding the glibc package...

CVE-2025-39815 RISC-V: KVM: fix stack overrun when loading vlenb

In the Linux kernel, the following vulnerability has been resolved: RISC-V: KVM: fix stack overrun when loading vlenb The userspace load can put up to 2048 bits into an xlen bit stack buffer. We want only xlen bits, so check the size beforehand...

Linux Kernel Security Vulnerabilities

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in Linux kernel that stems from unsafe reading of strings, which could lead to a crash during userspace address access...

CVE-2025-40300

The CVE-2025-40300 issue affects the Linux kernel’s x86/vmscape mitigation. The vulnerability arises from insufficient branch predictor isolation between a guest and a userspace hypervisor, which is mitigated by conditionally issuing an IBPB after VMexit and before returning to userspace. The fix...
