https://notcve.org/view.php?id=CVE-2022-48667
In the Linux kernel, the following vulnerability has been resolved: smb3: fix temporary data corruption in insert range insert range doesn't discard the affected cached region so can risk temporarily corrupting file data. Also includes some minor cleanup (avoiding rereading inode size repeatedly unnecessarily) to make it clearer. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: smb3: corrige la corrupción de datos temporales en el rango de inserción. El rango de inserción no descarta la región en caché afectada, por lo que puede correr el riesgo de dañar temporalmente los datos del archivo. También incluye una limpieza menor (evitando volver a leer el tamaño del inodo repetidamente innecesariamente) para hacerlo más claro. • https://git.kernel.org/stable/c/7fe6fe95b936084dce6eedcc2cccadf96eafae73 https://git.kernel.org/stable/c/0cdde8460c304283d4ebe3f767a70215d1ab9d4e https://git.kernel.org/stable/c/9c8b7a293f50253e694f19161c045817a938e551 •

https://notcve.org/view.php?id=CVE-2022-48666
In the Linux kernel, the following vulnerability has been resolved: scsi: core: Fix a use-after-free There are two .exit_cmd_priv implementations. Both implementations use resources associated with the SCSI host. Make sure that these resources are still available when .exit_cmd_priv is called by waiting inside scsi_remove_host() until the tag set has been freed.

In the Linux kernel, the following vulnerability has been resolved: exfat: fix overflow for large capacity partition Using int type for sector index, there will be overflow in a large capacity partition. For example, if storage with sector size of 512 bytes and partition capacity is larger than 2TB, there will be overflow. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: exfat: corrige el desbordamiento de una partición de gran capacidad. Al usar el tipo int para el índice del sector, habrá un desbordamiento en una partición de gran capacidad. Por ejemplo, si el almacenamiento con un tamaño de sector de 512 bytes y una capacidad de partición es superior a 2 TB, se producirá un desbordamiento. • https://git.kernel.org/stable/c/1b6138385499507147e8f654840f4c39afe6adbf https://git.kernel.org/stable/c/17244f71765dfec39e84493993993e896c376d09 https://git.kernel.org/stable/c/2e9ceb6728f1dc2fa4b5d08f37d88cbc49a20a62 •

In the Linux kernel, the following vulnerability has been resolved: gpio: mockup: fix NULL pointer dereference when removing debugfs We now remove the device's debugfs entries when unbinding the driver. This now causes a NULL-pointer dereference on module exit because the platform devices are unregistered *after* the global debugfs directory has been recursively removed. Fix it by unregistering the devices first. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: gpio: maqueta: corrige la desreferencia del puntero NULL al eliminar debugfs Ahora eliminamos las entradas debugfs del dispositivo al desvincular el controlador. Esto ahora provoca una desreferencia del puntero NULL al salir del módulo porque los dispositivos de la plataforma no están registrados *después* de que el directorio global debugfs se haya eliminado de forma recursiva. Solucionarlo cancelando el registro de los dispositivos primero. • https://git.kernel.org/stable/c/3815e66c2183f3430490e450ba16779cf5214ec6 https://git.kernel.org/stable/c/3a10e8edee2b45a654f1f7b05f747129ec84cf9d https://git.kernel.org/stable/c/bc55c1677edbe86a1c66a35e800df47dff16ad61 https://git.kernel.org/stable/c/bdea98b98f844bd8a983ca880893e509a8b4162f https://git.kernel.org/stable/c/18352095a0d581f6aeb1e9fc9d68cc0152cd64b4 https://git.kernel.org/stable/c/af0bfabf06c74c260265c30ba81a34e7dec0e881 https://git.kernel.org/stable/c/b7df41a6f79dfb18ba2203f8c5f0e9c0b9b57f68 •
