CVE-2024-27028

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: spi: spi-mt65xx: corrige el acceso al puntero NULL en el controlador de interrupciones. El búfer TX en spi_transfer puede ser un puntero NULL, por lo que el controlador de interrupciones puede terminar escribiendo en la memoria no válida y causar accidentes. Agregue una marca a trans->tx_buf antes de usarlo.

In the Linux kernel, the following vulnerability has been resolved: spi: spi-mt65xx: Fix NULL pointer access in interrupt handler The TX buffer in spi_transfer can be a NULL pointer, so the interrupt handler may end up writing to the invalid memory and cause crashes. Add a check to trans->tx_buf before using it.

Ziming Zhang discovered that the DRM driver for VMware Virtual GPU did not properly handle certain error conditions, leading to a NULL pointer dereference. A local attacker could possibly trigger this vulnerability to cause a denial of service. Zheng Wang discovered that the Broadcom FullMAC WLAN driver in the Linux kernel contained a race condition during device removal, leading to a use- after-free vulnerability. A physically proximate attacker could possibly use this to cause a denial of service.
