CVE-2026-72039

In the Linux kernel, the following vulnerability has been resolved: bnx2x: fix potential memory leak in bnx2xallocmembp If the allocation of fpi.tpainfo fails, the error path will not free the struct bnx2xfastpath allocated earlier, as it is not linked to the bp structure yet. Fix that by linking...

CVE-2026-72039

The CVE-2026-72039 entry concerns the Linux kernel bug in the bnx2x driver where a potential memory leak could occur during bnx2x_alloc_mem_bp() if fp[i].tpa_info allocation fails. The fix is to link the newly allocated struct bnx2x_fastpath immediately after allocation so it is freed on error pa...

CVE-2026-64284

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM for x86 systems. This vulnerability occurs when KVM handles fastpath exits, where it may fail to execute vendor-specific cleanup operations before returning control to the virtual machine's userspace. Consequently, memory...

CVE-2026-64284

CVE-2026-64284 — Linux kernel (KVM/x86): The vulnerability involves moving the handling of fastpath userspace exits into vendor code so KVM can run vendor-specific operations before userspace gains control of the vCPU. The description notes that, for VMX (and soon SVM), KVM must flush the PML buf...

PT-2026-64505

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the KVM x86 module where fastpath userspace exits may occur before the vendor's exit handler runs. This prevents KVM from executing vendor-specific operations required...

PYSEC-2026-2029 Vyper's `concat()` builtin may elide side-effects for zero-length arguments

Impact concat may skip evaluation of side effects when the length of an argument is zero. this is due to a fastpath in the implementation which skips evaluation of argument expressions when their length is zero:...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: KVM: SVM: Skip fastpath emulation on VM-Exit if next RIP isn’t valid Skip the WRMSR and HLT fastpaths in SVM’s VM-Exit handler if the next RIP isn’t valid, for example, because KVM is running with nrips=false. SVM must decode and...
