https://notcve.org/view.php?id=CVE-2022-48720
In the Linux kernel, the following vulnerability has been resolved: net: macsec: Fix offload support for NETDEV_UNREGISTER event Current macsec netdev notify handler handles NETDEV_UNREGISTER event by releasing relevant SW resources only, this causes resources leak in case of macsec HW offload, as the underlay driver was not notified to clean it's macsec offload resources. Fix by calling the underlay driver to clean it's relevant resources by moving offload handling from macsec_dellink() to macsec_common_dellink() when handling NETDEV_UNREGISTER event. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: macsec: se corrigió el soporte de descarga para el evento NETDEV_UNREGISTER. El controlador de notificación netdev de macsec actual maneja el evento NETDEV_UNREGISTER liberando solo recursos SW relevantes, lo que provoca una pérdida de recursos en caso de descarga de HW de macsec, ya que No se notificó al controlador subyacente que limpiara sus recursos de descarga de macsec. Para solucionarlo, llame al controlador subyacente para limpiar sus recursos relevantes moviendo el manejo de descarga de macsec_dellink() a macsec_common_dellink() cuando se maneja el evento NETDEV_UNREGISTER. • https://git.kernel.org/stable/c/3cf3227a21d1fb020fe26128e60321bd2151e922 https://git.kernel.org/stable/c/2e7f5b6ee1a7a2c628253a95b0a95b582901ef1b https://git.kernel.org/stable/c/e7a0b3a0806dae3cc81931f0e83055ca2ac6f455 https://git.kernel.org/stable/c/8299be160aad8548071d080518712dec0df92bd5 https://git.kernel.org/stable/c/9cef24c8b76c1f6effe499d2f131807c90f7ce9a •

In the Linux kernel, the following vulnerability has been resolved: drm: mxsfb: Fix NULL pointer dereference mxsfb should not ever dereference the NULL pointer which drm_atomic_get_new_bridge_state is allowed to return. Assume a fixed format instead. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: drm: mxsfb: corrige la desreferencia del puntero NULL. mxsfb nunca debería desreferenciar el puntero NULL que drm_atomic_get_new_bridge_state puede devolver.

In the Linux kernel, the following vulnerability has been resolved: ASoC: max9759: fix underflow in speaker_gain_control_put() Check for negative values of "priv->gain" to prevent an out of bounds access. The concern is that these might come from the user via: -> snd_ctl_elem_write_user() -> snd_ctl_elem_write() -> kctl->put() En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ASoC: max9759: corrige el desbordamiento en altavoz_gain_control_put() Compruebe si hay valores negativos de "priv->gain" para evitar un acceso fuera de los límites.

In the Linux kernel, the following vulnerability has been resolved: ASoC: codecs: wcd938x: fix incorrect used of portid Mixer controls have the channel id in mixer->reg, which is not same as port id. port id should be derived from chan_info array. So fix this. Without this, its possible that we could corrupt struct wcd938x_sdw_priv by accessing port_map array out of range with channel id instead of port id. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: ASoC: códecs: wcd938x: corrige el uso incorrecto del puerto Los controles del mezclador tienen la identificación del canal en mezclador->reg, que no es la misma que la identificación del puerto. La identificación del puerto debe derivarse de la matriz chan_info.
