https://notcve.org/view.php?id=CVE-2023-52453
In the Linux kernel, the following vulnerability has been resolved: hisi_acc_vfio_pci: Update migration data pointer correctly on saving/resume When the optional PRE_COPY support was added to speed up the device compatibility check, it failed to update the saving/resuming data pointers based on the fd offset. This results in migration data corruption and when the device gets started on the destination the following error is reported in some cases, [ 478.907684] arm-smmu-v3 arm-smmu-v3.2.auto: event 0x10 received: [ 478.913691] arm-smmu-v3 arm-smmu-v3.2.auto: 0x0000310200000010 [ 478.919603] arm-smmu-v3 arm-smmu-v3.2.auto: 0x000002088000007f [ 478.925515] arm-smmu-v3 arm-smmu-v3.2.auto: 0x0000000000000000 [ 478.931425] arm-smmu-v3 arm-smmu-v3.2.auto: 0x0000000000000000 [ 478.947552] hisi_zip 0000:31:00.0: qm_axi_rresp [error status=0x1] found [ 478.955930] hisi_zip 0000:31:00.0: qm_db_timeout [error status=0x400] found [ 478.955944] hisi_zip 0000:31:00.0: qm sq doorbell timeout in function 2 En el kernel de Linux, se resolvió la siguiente vulnerabilidad: hisi_acc_vfio_pci: actualiza correctamente el puntero de datos de migración al guardar/reanudar Cuando se agregó el soporte PRE_COPY opcional para acelerar la verificación de compatibilidad del dispositivo, no se pudieron actualizar los punteros de datos de guardado/reanudación según el desplazamiento fd.

https://notcve.org/view.php?id=CVE-2024-26593
In the Linux kernel, the following vulnerability has been resolved: i2c: i801: Fix block process call transactions According to the Intel datasheets, software must reset the block buffer index twice for block process call transactions: once before writing the outgoing data to the buffer, and once again before reading the incoming data from the buffer. The driver is currently missing the second reset, causing the wrong portion of the block buffer to be read. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: i2c: i801: Reparar transacciones de llamada de proceso de bloque Según las hojas de datos de Intel, el software debe restablecer el índice del búfer de bloque dos veces para transacciones de llamada de proceso de bloque: una vez antes de escribir los datos salientes en el búfer , y una vez más antes de leer los datos entrantes del búfer. Actualmente, al controlador le falta el segundo reinicio, lo que provoca que se lea la parte incorrecta del búfer de bloque. • https://git.kernel.org/stable/c/315cd67c945351f8a569500f8ab16b7fa94026e8 https://git.kernel.org/stable/c/d074d5ff5ae77b18300e5079c6bda6342a4d44b7 https://git.kernel.org/stable/c/7a14b8a477b88607d157c24aeb23e7389ec3319f https://git.kernel.org/stable/c/1f8d0691c50581ba6043f009ec9e8b9f78f09d5a https://git.kernel.org/stable/c/491528935c9c48bf341d8b40eabc6c4fc5df6f2c https://git.kernel.org/stable/c/6be99c51829b24c914cef5bff6164877178e84d9 https://git.kernel.org/stable/c/609c7c1cc976e740d0fed4dbeec688b3ecb5dce2 https://git.kernel.org/stable/c/c1c9d0f6f7f1dbf29db996bd8e1662428 • CWE-125: Out-of-bounds Read •
