Vulnerabilidades

An unencrypted 'pause encryption request' message causes a denial of service in the in the RS9116W/SiWx917. See vulnerability B-E10 in the related paper below.

The Silicon Labs SiWx917 WiFi driver's transmit callback siwx91x_send() in drivers/wifi/siwx91x/siwx91x_wifi.c frees a network packet it does not own. In the Zephyr TX path the net_pkt is owned by the L2/networking stack; the driver only borrows it to copy the frame bytes into a local net_buf. Before the fix, after…

A malformed Bluetooth connection request message can cause the RS9116W/SiWx917 to leak potentially sensitive information. See vulnerability B-E4 in the related paper below.

Passkey entry Bluetooth LE legacy pairing can be bypassed in the RS9116W and SiWx917 by manipulating the temporary key value. See vulnerability B-E3 in the related paper below.

Spoofing an already bonded device can force either RS9116W or SiWx917 to re-pair/bond with a rogue device. See V1 in BLERP paper below

A bug in the entropy initialization for SiWx917 causes the DRBG to use a predictable seed. As such, all random numbers generated in the Matter code use the same stream of numbers. This vulnerability was discovered after the impacted repository was already deprecated.
