In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Fix an out-of-bounds bug in __snd_usb_parse_audio_interface() There may be a bad USB audio device with a USB ID of (0x04fa, 0x4201) and the number of it's interfaces less than 4, an out-of-bounds read bug occurs when parsing the interface descriptor for this device. Fix this by checking the number of interfaces. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ALSA: usb-audio: corrige un error fuera de los límites en __snd_usb_parse_audio_interface() Puede haber un dispositivo de audio USB defectuoso con una ID de USB de (0x04fa, 0x4201) y el Si el número de interfaces es inferior a 4, se produce un error de lectura fuera de límites al analizar el descriptor de interfaz para este dispositivo. Solucione este problema verificando la cantidad de interfaces. • https://git.kernel.org/stable/c/b970518014f2f0f6c493fb86c1e092b936899061 https://git.kernel.org/stable/c/91904870370fd986c29719846ed76d559de43251 https://git.kernel.org/stable/c/2a308e415d247a23d4d64c964c02e782eede2936 https://git.kernel.org/stable/c/0492798bf8dfcc09c9337a1ba065da1d1ca68712 https://git.kernel.org/stable/c/6123bec8480d23369e2ee0b2208611619f269faf https://git.kernel.org/stable/c/98e8e67395cc6d0cdf3a771f86ea42d0ee6e59dd https://git.kernel.org/stable/c/8293e61bbf908b18ff9935238d4fc2ad359e3fe0 https://git.kernel.org/stable/c/e53f47f6c1a56d2af728909f1cb894da6 •

https://notcve.org/view.php?id=CVE-2022-48699
In the Linux kernel, the following vulnerability has been resolved: sched/debug: fix dentry leak in update_sched_domain_debugfs Kuyo reports that the pattern of using debugfs_remove(debugfs_lookup()) leaks a dentry and with a hotplug stress test, the machine eventually runs out of memory. Fix this up by using the newly created debugfs_lookup_and_remove() call instead which properly handles the dentry reference counting logic. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: sched/debug: corrige la fuga de dentry en update_sched_domain_debugfs Kuyo informa que el patrón de uso de debugfs_remove(debugfs_lookup()) pierde un dentry y con una prueba de estrés de conexión en caliente, la máquina eventualmente se queda sin memoria. Solucione este problema utilizando la llamada debugfs_lookup_and_remove() recién creada, que maneja adecuadamente la lógica de conteo de referencias de dentry. • https://git.kernel.org/stable/c/26e9a1ded8923510e5529fbb28390b22228700c2 https://git.kernel.org/stable/c/0c32a93963e03c03e561d5a066eedad211880ba3 https://git.kernel.org/stable/c/c2e406596571659451f4b95e37ddfd5a8ef1d0dc •

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: fix memory leak when using debugfs_lookup() When calling debugfs_lookup() the result must have dput() called on it, otherwise the memory will leak over time. Fix this up by properly calling dput().

CVSS: 5.5EPSS: 0%CPEs: 2EXPL: 0CVE-2022-48696 – regmap: spi: Reserve space for register address/padding
https://notcve.org/view.php?id=CVE-2022-48696
In the Linux kernel, the following vulnerability has been resolved: regmap: spi: Reserve space for register address/padding Currently the max_raw_read and max_raw_write limits in regmap_spi struct do not take into account the additional size of the transmitted register address and padding. This may result in exceeding the maximum permitted SPI message size, which could cause undefined behaviour, e.g. data corruption. Fix regmap_get_spi_bus() to properly adjust the above mentioned limits by reserving space for the register address/padding as set in the regmap configuration. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: regmap: spi: reserva de espacio para dirección/relleno de registro Actualmente, los límites max_raw_read y max_raw_write en la estructura regmap_spi no tienen en cuenta el tamaño adicional de la dirección de registro transmitida y el relleno. Esto puede dar como resultado que se exceda el tamaño de mensaje SPI máximo permitido, lo que podría causar un comportamiento indefinido, por ejemplo, corrupción de datos. Corrija regmap_get_spi_bus() para ajustar adecuadamente los límites mencionados anteriormente reservando espacio para la dirección/relleno del registro como se establece en la configuración de regmap. • https://git.kernel.org/stable/c/f231ff38b7b23197013b437128d196710fe282da https://git.kernel.org/stable/c/15ff1f17847c19174b260bd7dd0de33edcebd45e https://git.kernel.org/stable/c/f5723cfc01932c7a8d5c78dbf7e067e537c91439 https://access.redhat.com/security/cve/CVE-2022-48696 https://bugzilla.redhat.com/show_bug.cgi?id=2278959 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
