https://notcve.org/view.php?id=CVE-2022-49568
26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: KVM: Don't null dereference ops->destroy A KVM device cleanup happens in either of two callbacks: 1) destroy() which is called when the VM is being destroyed; 2) release() which is called when a device fd is closed. Most KVM devices use 1) but Book3s's interrupt controller KVM devices (XICS, XIVE, XIVE-native) use 2) as they need to close and reopen during the machine execution. The error handling in kvm_ioctl_create_device() assumes destro... • https://git.kernel.org/stable/c/170465715a60cbb7876e6b961b21bd3225469da8 •

Replace the explicit calls to free the buffers in qat_rsa_exit_tfm() with a call to qat_rsa_clear_ctx() which frees all buffers referenced in the TFM context.

The VM_PFNMAP path is broken as it assumes that vm_pgoff is the base pfn of the mapped VMA range, which is conceptually wrong as vm_pgoff is the offset relative to the file and has nothing to do with the pfn.

This is commonly triggered by code calling del_timer() instead of del_timer_sync() just before freeing. One possible culprit is the hci_qca driver, which does exactly that.

26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: zsmalloc: fix races between asynchronous zspage free and page migration The asynchronous zspage free worker tries to lock a zspage's entire page list without defending against page migration. Since pages which haven't yet been locked can concurrently migrate off the zspage page list while lock_zspage() churns away, lock_zspage() can suffer from a few different lethal races. It can lock a page which no longer belongs to the zspage and unsafe... • https://git.kernel.org/stable/c/77ff465799c60294e248000cd22ae8171da3304c •
