In all android releases (Android for MSM, Firefox OS for MSM, QRD Android) from CAF using the linux kernel, LUT configuration is passed down to driver from userspace via ioctl. Simultaneous update from userspace while kernel drivers are updating LUT registers can lead to race condition.Show less

In all android releases (Android for MSM, Firefox OS for MSM, QRD Android) from CAF using the linux kernel, lack of check of input received from userspace before copying into buffer can lead to potential array overflow in WLAN.Show less

In all android releases (Android for MSM, Firefox OS for MSM, QRD Android) from CAF using the linux kernel, callback executed from the other thread has freed memory which is also used in wlan function and may result in to a "Use after free" scenario.Show less

In all android releases (Android for MSM, Firefox OS for MSM, QRD Android) from CAF using the linux kernel, when WLAN FW has not filled the vdev id correctly in stats events then WLAN host driver tries to access interface array without proper bound check which can lead to invalid memory access and as a side effect kernel panic or page fault.Show less

In all android releases (Android for MSM, Firefox OS for MSM, QRD Android) from CAF using the linux kernel, while processing SET_PASSPOINT_LIST vendor command HDD does not make sure that the realm string that gets passed by upper-layer is NULL terminated. This may lead to buffer overflow as strlen is used to get realm string length to construct the PASSPOINT WMA command.Show less

In all android releases (Android for MSM, Firefox OS for MSM, QRD Android) from CAF using the linux kernel, a buffer over-read can occur In the WMA NDP event handler functions due to lack of validation of input value event_info which is received from FW.Show less

In all android releases (Android for MSM, Firefox OS for MSM, QRD Android) from CAF using the linux kernel, WMA handler carries a fixed event data from the firmware to the host . If the length and anqp length from this event data exceeds the max length, an OOB write would happen.Show less

In all android releases (Android for MSM, Firefox OS for MSM, QRD Android) from CAF using the linux kernel, WLAN handler indication from the firmware gets the information for 4 access categories. While processing this information only the first 3 AC information is copied due to the improper conditional logic used to compare with the max number of categories.Show less

In all android releases (Android for MSM, Firefox OS for MSM, QRD Android) from CAF using the linux kernel, in wma_ndp_confirm_event_handler and wma_ndp_indication_event_handler, ndp_cfg len and num_ndp_app_info is from fw. If they are not checked, it may cause buffer over-read once the value is too large.Show less

In all android releases (Android for MSM, Firefox OS for MSM, QRD Android) from CAF using the linux kernel, while calling IPA_IOC_MDFY_RT_RULE IPA IOCTL, header entry is not checked before use. If IPA_IOC_MDFY_RT_RULE IOCTL called for header entries formerly deleted, a Use after free condition will occur.Show less

In all android releases (Android for MSM, Firefox OS for MSM, QRD Android) from CAF using the linux kernel, while processing user-space there is no size validation of the NAT entry input. If the user input size of the NAT entry is greater than the max allowed size, memory exhaustion will occur.Show less

In all android releases (Android for MSM, Firefox OS for MSM, QRD Android) from CAF using the linux kernel, Venus HW searches for start code when decoding input bit stream buffers. If start code is not found in entire buffer, there is over-fetch beyond allocation length. This leads to page fault.Show less

In all android releases (Android for MSM, Firefox OS for MSM, QRD Android) from CAF using the linux kernel, double free of memory allocation is possible in Kernel when it explicitly tries to free that memory on driver probe failure, since memory allocated is automatically freed on probe.Show less
