CVE-2024-35821

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ubifs: establece la actualización de la página en el lugar correcto. Las lecturas de la caché de la página no tienen bloqueo, por lo que configurar la actualización de la página recién asignada antes de que la sobrescribamos con los datos que se supone que debe contener lo hará. permitir que un lector simultáneo vea datos antiguos. Mueva la llamada a SetPageUptodate a ubifs_write_end(), que es después de que copiamos los nuevos datos en la página.

In the Linux kernel, the following vulnerability has been resolved: ubifs: Set page uptodate in the correct place Page cache reads are lockless, so setting the freshly allocated page uptodate before we've overwritten it with the data it's supposed to have in it will allow a simultaneous reader to see old data. Move the call to SetPageUptodate into ubifs_write_end(), which is after we copied the new data into the page.

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.
