CVSS: 5.5EPSS: 0%CPEs: 4EXPL: 0CVE-2023-52648 – drm/vmwgfx: Unmap the surface before resetting it on a plane state
https://notcve.org/view.php?id=CVE-2023-52648
In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: Unmap the surface before resetting it on a plane state Switch to a new plane state requires unreferencing of all held surfaces. In the work required for mob cursors the mapped surfaces started being cached but the variable indicating whether the surface is currently mapped was not being reset. This leads to crashes as the duplicated state, incorrectly, indicates the that surface is mapped even when no surface is present. That's because after unreferencing the surface it's perfectly possible for the plane to be backed by a bo instead of a surface. Reset the surface mapped flag when unreferencing the plane state surface to fix null derefs in cleanup.

https://notcve.org/view.php?id=CVE-2023-52647
In the Linux kernel, the following vulnerability has been resolved: media: nxp: imx8-isi: Check whether crossbar pad is non-NULL before access When translating source to sink streams in the crossbar subdev, the driver tries to locate the remote subdev connected to the sink pad. The remote pad may be NULL, if userspace tries to enable a stream that ends at an unconnected crossbar sink. When that occurs, the driver dereferences the NULL pad, leading to a crash. Prevent the crash by checking if the pad is NULL before using it, and return an error if it is. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: media: nxp: imx8-isi: compruebe si el crossbar pad no es NULL antes del acceso. Al traducir el código fuente a las secuencias receptoras en el subdev de la barra transversal, el controlador intenta localizar el subdev remoto conectado a la plataforma del fregadero. • https://git.kernel.org/stable/c/cf21f328fcafacf4f96e7a30ef9dceede1076378 https://git.kernel.org/stable/c/c95318607fbe8fdd44991a8dad2e44118e6b8812 https://git.kernel.org/stable/c/c4bd29bf5b7f67925bc1abd16069f22dadf5f061 https://git.kernel.org/stable/c/91c8ce42fcde09f1da24acab9013b3e19cb88a4e https://git.kernel.org/stable/c/eb2f932100288dbb881eadfed02e1459c6b9504c •
