CVE-2024-53189
Full vulnerability record from the local CVENow database.
Description
In the Linux kernel, the following vulnerability has been resolved: wifi: nl80211: fix bounds checker error in nl80211_parse_sched_scan The channels array in the cfg80211_scan_request has a __counted_by attribute attached to it, which points to the n_channels variable. This attribute is used in bounds checking, and if it is not set before the array is filled, then the bounds sanitizer will issue a warning or a kernel panic if CONFIG_UBSAN_TRAP is set. This patch sets the size of allocated memory as the initial value for n_channels. It is updated with the actual number of added elements after the array is filled.

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: wifi: nl80211: fix bounds checker error in nl80211_parse_sched_scan La matriz channels en cfg80211_scan_request tiene un atributo __counted_by adjunto, que apunta a la variable n_channels. Este atributo se utiliza en la comprobación de los límites y, si no se configura antes de que se complete la matriz, el desinfectante de los límites emitirá una advertencia o un pánico del kernel si se configura CONFIG_UBSAN_TRAP. Este parche establece el tamaño de la memoria asignada como el valor inicial para n_channels. Se actualiza con el número real de elementos agregados después de que se complete la matriz."
