CVE-2015-4001

CRITICAL9.0

Integer signedness error in the oz_hcd_get_desc_cnf function in drivers/staging/ozwpan/ozhcd.c in the OZWPAN driver in the Linux kernel through 4.0.5 allows remote attackers to cause a denial of service (system crash) or possibly execute arbitrary code via a crafted packet.

CVE-2015-4002

CRITICAL9.0

drivers/staging/ozwpan/ozusbsvc1.c in the OZWPAN driver in the Linux kernel through 4.0.5 does not ensure that certain length values are sufficiently large, which allows remote attackers to cause a denial of service (system crash or large loop) or possibly execute arbitrary code via a crafted packet, related to the (1) oz_usb_rx and (2) oz_usb_handle_ep_data functions.

CVE-2015-4003

HIGH7.8

The oz_usb_handle_ep_data function in drivers/staging/ozwpan/ozusbsvc1.c in the OZWPAN driver in the Linux kernel through 4.0.5 allows remote attackers to cause a denial of service (divide-by-zero error and system crash) via a crafted packet.

MEDIUM4.9

The bpf_int_jit_compile function in arch/x86/net/bpf_jit_comp.c in the Linux kernel before 4.0.6 allows local users to cause a denial of service (system crash) by creating a packet filter and then loading crafted BPF instructions that trigger late convergence by the JIT compiler.

CVE-2015-5364

HIGH7.8

The (1) udp_recvmsg and (2) udpv6_recvmsg functions in the Linux kernel before 4.0.6 do not properly consider yielding a processor, which allows remote attackers to cause a denial of service (system hang) via incorrect checksums within a UDP packet flood.

CVE-2015-5366

MEDIUM5.0

The (1) udp_recvmsg and (2) udpv6_recvmsg functions in the Linux kernel before 4.0.6 provide inappropriate -EAGAIN return values, which allows remote attackers to cause a denial of service (EPOLLET epoll application read outage) via an incorrect checksum in a UDP packet, a different vulnerability than CVE-2015-5364.
