CVE-2017-1000253

CVE-2017-1000253 is a Linux kernel PIE stack buffer corruption vulnerability in load_elf_binary() that can allow local privilege escalation when PIE is used and memory mapping overlaps the stack region. The issue stems from not accounting for space for the entire binary, causing later PT_LOAD seg...

CVE-2017-7308

CVE-2017-7308 applies to the Linux kernel AF_PACKET packet_set_ring implementation. The issue arises from insufficient validation of certain block-size data in net/packet/af_packet.c, enabling a local user with CAP_NET_RAW to trigger a denial of service (integer signedness error and out-of-bounds...

CVE-2017-6074

CVE-2017-6074 affects the Linux kernel up to 4.9.11, where dccp_rcv_state_process in net/dccp/input.c mishandles DCCP_PKT_REQUEST data in LISTEN state. This can allow a local user to gain root privileges or trigger a denial of service (double free) via an application using IPV6_RECVPKTINFO setsoc...

CVE-2016-10229

The CVE-2016-10229 issue affects the Linux kernel’s UDP handling: udp.c in versions before 4.5 contains an unsafe second checksum calculation when a recv call uses MSG_PEEK, enabling remote code execution. Reports and advisories (e.g., ALAS-2017-832, Alpine, Debian, Broadcom/Big-IP advisories) co...

CVE-2017-7184

The CVE-2017-7184 issue affects the Linux kernel xfrm subsystem, where xfrm_replay_verify_len in net/xfrm/xfrm_user.c up to 4.10.6 does not validate certain size data after an XFRM_MSG_NEWAE update, enabling a local attacker with CAP_NET_ADMIN to cause a heap-based out-of-bounds access and potent...

CVE-2017-7645

The CVE-2017-7645 issue affects the Linux kernel NFSv2/v3 server (nfsd) and is triggered by processing long RPC replies. The root cause is an out-of-bounds memory access in the NFS server paths (net/sunrpc/svc.c, fs/nfsd/nfs3xdr.c, fs/nfsd/nfsxdr.c) that can lead to a system crash (DoS). Affected...

CVE-2017-2636

CVE-2017-2636 details (NORMAL mode) : A race condition in the Linux kernel N_HLDC driver (n_hdlc) can lead to a double free. A local, unprivileged user who sets the HDLC line discipline on a tty device could exploit this to escalate privileges or cause a denial of service (system crash). Exploita...

CVE-2017-7889

CVE-2017-7889 affects the Linux kernel mm subsystem (up to 3.2); a local attacker with access to /dev/mem can read/write kernel memory due to CONFIG_STRICT_DEVMEM not being properly enforced in arch/x86/mm/init.c and drivers/char/mem.c. Public details: Debian security advisories show fixes (e.g.,...

CVE-2016-10200

CVE-2016-10200 describes a race condition in the Linux kernel’s L2TPv3 IP Encapsulation feature that can allow a local user to escalate privileges or cause a denial of service via repeated bind() calls without correctly checking SOCK_ZAPPED status. The issue affects Linux kernels prior to 4.8.14,...

CVE-2017-5897

CVE-2017-5897 involves an out-of-bounds read in the Linux kernel’s IPv6 GRE handling (ip6_gre.c, ip6gre_err). Connected sources (Debian DSA-3791-1 and Cloud Foundry USN-3265-2) confirm the issue and note mitigation via kernel updates (e.g., Debian Jessie fix in linux 3.16.39-1+deb8u1; vendor advi...

CVE-2017-6346

CVE-2017-6346 affects the Linux kernel net/packet/af_packet.c, describing a race condition in the PACKET_FANOUT fanout path that can cause a use-after-free in multithreaded user apps. The connected sources confirm this is a local vulnerability with potential denial of service and possible unspeci...

CVE-2017-7294

The CVE-2017-7294 issue affects the Linux kernel up to 4.10.6, specifically vmwgfx vmw_surface_define_ioctl() in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c. A crafted ioctl to /dev/dri/renderD* can trigger an integer overflow and out-of-bounds write, causing denial of service (system hang/crash) and...

CVE-2014-9914

Summary of CVE-2014-9914 (Linux kernel) : A race condition in ip4_datagram_release_cb within net/ipv4/datagram.c (kernel before 3.15.2) can be exploited by a local user to gain privileges or cause a denial of service (use-after-free) due to incorrect locking assumptions during multithreaded IPv4 ...

CVE-2016-9754

CVE-2016-9754 affects the Linux kernel’s ring_buffer_resize in the profiling subsystem, where integer calculations in ring_buffer.c before 4.6.1 allow a local user to gain privileges by writing to /sys/kernel/debug/tracing/buffer_size_kb. The issue is fixed in kernel 4.6.1 and later. Affected pro...

CVE-2017-8106

The CVE-2017-8106 issue affects the Linux kernel (arch/x86/kvm/vmx.c) in versions 3.12–3.15. The vulnerability arises from the handle_invept path, enabling privileged KVM guest OS users to trigger a NULL pointer dereference via a single-context INVEPT with a NULL EPT pointer, causing a denial of ...
