Descriptions

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: check/clear fast rx for non-4addr sta VLAN changes When moving a station out of a VLAN and deleting the VLAN afterwards, the
fast_rx entry still holds a pointer to the VLAN's netdev, which can cause
use-after-free bugs. Fix this by immediately calling ieee80211_check_fast_rx
after the VLAN change.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: wifi: mac80211: comprobar/borrar fast rx para cambios de VLAN que no sean 4addr sta Al mover una estación fuera de una VLAN y eliminar la VLAN después, la entrada fast_rx todavía contiene un puntero a netdev de la VLAN, lo que puede causar errores de uso después de la liberación. Solucione este problema llamando inmediatamente a ieee80211_check_fast_rx después del cambio de VLAN.

CVE-2024-35789 is a vulnerability in the Linux kernel’s Wi-Fi subsystem (mac80211). It occurs when a station is moved out of a VLAN, and the VLAN is subsequently deleted. A reference to the deleted VLAN’s network device may remain, leading to a use-after-free condition. This can result in system instability or crashes. The issue has been resolved by ensuring that outdated references are cleared when a station changes VLANs.

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: check/clear fast rx for non-4addr sta VLAN changes When moving a station out of a VLAN and deleting the VLAN afterwards, the fast_rx entry still holds a pointer to the VLAN's netdev, which can cause use-after-free bugs. Fix this by immediately calling ieee80211_check_fast_rx after the VLAN change.

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.
