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 •

CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2024-26926 – binder: check offset alignment in binder_get_object()
https://notcve.org/view.php?id=CVE-2024-26926
In the Linux kernel, the following vulnerability has been resolved: binder: check offset alignment in binder_get_object() Commit 6d98eb95b450 ("binder: avoid potential data leakage when copying txn") introduced changes to how binder objects are copied. In doing so, it unintentionally removed an offset alignment check done through calls to binder_alloc_copy_from_buffer() -> check_buffer(). These calls were replaced in binder_get_object() with copy_from_user(), so now an explicit offset alignment check is needed here. This avoids later complications when unwinding the objects gets harder. It is worth noting this check existed prior to commit 7a67a39320df ("binder: add function to copy binder object from buffer"), likely removed due to redundancy at the time. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: Binder: verifique la alineación de desplazamiento en binder_get_object() El commit 6d98eb95b450 ("binder: evite posibles fugas de datos al copiar txn") introdujo cambios en la forma en que se copian los objetos de Binder. Al hacerlo, eliminó involuntariamente una verificación de alineación de desplazamiento realizada mediante llamadas a binder_alloc_copy_from_buffer() -> check_buffer(). • https://git.kernel.org/stable/c/c056a6ba35e00ae943e377eb09abd77a6915b31a https://git.kernel.org/stable/c/23e9d815fad84c1bee3742a8de4bd39510435362 https://git.kernel.org/stable/c/7a9ad4aceb0226b391c9d3b8e4ac2e7d438b6bde https://git.kernel.org/stable/c/6d98eb95b450a75adb4516a1d33652dc78d2b20c https://git.kernel.org/stable/c/66e12f5b3a9733f941893a00753b10498724607d https://git.kernel.org/stable/c/68a28f551e4690db2b27b3db716c7395f6fada12 https://git.kernel.org/stable/c/48a1f83ca9c68518b1a783c62e6a8223144fa9fc https://git.kernel.org/stable/c/a2fd6dbc98be1105a1d8e9e31575da887 •
