Elevation of Privilege in Broadcom Wi-Fi Driver The wl_escan_handler() function of the Broadcom wireless driver has insufficient checks for integer overflows. A bad request from the wireless firmware could cause insufficient memory allocation, memory overflows, and arbitrary code execution. CVE-2017-0786
Elevation of Privilege in Broadcom Wi-Fi Driver The dhd_pno_process_epno_result() function of the Broadcom wireless driver multiplies an unsigned count value by sizeof(dhd_epno_results_t) to get the size of a memory allocation.

CVE-2017-0787
Elevation of Privilege in Broadcom Wi-Fi Driver The dhd_handle_swc_evt() function of the Broadcom wireless driver allocates memory before checking for some failure cases. In those failure cases, the allocated memory is preserved, but the required size can be changed before calling the function again, but the old allocation is used. If the new size is larger, the allocated buffer might overflow, leading to kernel memory corruption and potential arbitrary code execution. CVE-2017-0789
Elevation of Privilege in Broadcom Wi-Fi Driver The dhd_process_full_gscan_result() function of the Broadcom wireless driver does not check for integer overflow when using the bi_length parameter.

Information Disclosure in Broadcom Wi-Fi Driver The dhd_rtt_event_handler() function of the Broadcom wireless driver does not properly check the tlvs_len parameter of incoming event data. A bad event from the wireless firmware could cause an out-of-bounds read in mapped kernel memory. CVE-2017-0792
Remote Code Execution in Kernel The inet_csk_clone_lock() function has a double-free vulnerability that can be triggered by a remote attacker. CVE-2017-8890
Elevation of Privilege in Kernel The dccp_v6_request_recv_sock function in net/dccp/ipv6.c in the Linux kernel through 4.11.1 mishandles inheritance, which allows local users to cause memory corruption that might lead to arbitrary code execution. CVE-2017-9076
Information Disclosure in Kernel The do_check function in kernel/bpf/verifier.c in the Linux kernel before 4.11.1 does not make the allow_ptr_leaks value available for restricting the output of the print_bpf_insn function, which allows local users to obtain sensitive address information via crafted bpf system calls. CVE-2017-9150
Elevation of Privilege in Kernel IPX protocol Driver The ipxitf_ioctl function in net/ipx/af_ipx.c in the Linux kernel through 4.11.1 mishandles reference counts, which allows local users to cause use-after-free errors or other memory corruption. CVE-2017-7487
Denial of Service in Kernel The tcp_splice_read function in net/ipv4/tcp.c in the Linux kernel before 4.9.11 allows remote attackers to cause a denial of service (infinite loop and soft lockup) via vectors involving a TCP packet with the URG flag. CVE-2017-6214
Elevation of Privilege in Kernel The fanout_add() function does not have sufficient mutex locking around using shared packet_rollover objects. Concurrent use could lead to use-after-free errors or other kernel memory corruption, enabling arbitrary code execution. CVE-2017-6346
Information Disclosure in Kernel The ip6gre_err() function does not properly account for the length of the IPv6 header, and reads kernel memory outside the bounds of incoming data. CVE-2017-5897
Information Disclosure in Kernel File System In the ext4 filesystem implementation, a crash can interrupt the journal write after the data itself is written. An attacker that creates a new file after a crash may gain access to that data. CVE-2017-7495
Information Disclosure in Kernel Incorrect error handling in the set_mempolicy and mbind compat syscalls in mm/mempolicy.c in the Linux kernel through 4.10.9 allows local users to obtain sensitive information from uninitialized stack data by triggering failure of a certain bitmap operation. CVE-2017-7616
Elevation of Privilege in Kernel SCSI Driver The sg_ioctl() function does not have sufficient mutex protection around global data writes. Concurrent access to this ioctl can cause use-after-free errors, double-free errors, and other memory corruption issues in the kernel that could lead to arbitrary code execution. CVE-2017-0794
Elevation of Privilege in Qualcomm Memory subSystem Passing in too large a value into the ION memory allocator results in the integer being truncated, leading to memory corruption. CVE-2017-9725
Elevation of Privilege in Qualcomm The ION driver allows the user to specify an address (possibly in kernel space) to write a NULL to. CVE-2017-9724

Elevation of Privilege in Qualcomm Camera Driver In the camera driver, the num_streams value passed to msm_isp_check_stream_cfg_cmd and msm_isp_stats_update_cgc_override wasn’t bounds checked, resulting in a possible out-of-bounds write. CVE-2017-8251
Elevation of Privilege in Qualcomm Camera Driver The reference count on the camera driver has some operations that aren’t sufficiently atomic. CVE-2017-8247
Elevation of Privilege in Qualcomm Camera Driver In the msm_isp_update_stats_stream function in the camera driver, there is a possible out-of-bounds write due to an incorrect bounds check. CVE-2017-9720
Elevation of Privilege in Qualcomm Video Driver In the function msm_dba_register_client, if the client registration failed, it would be freed. However, the client was not removed from the list. Use-after-free would occur when traversing the list next time. CVE-2017-8277
