Linux vulnerabilities

drivers/tty/n_tty.c in the Linux kernel before 4.14.11 allows local attackers (who are able to access pseudo terminals) to hang/block further usage of any pseudo terminal devices due to an EXTPROC versus ICANON confusion in TIOCINQ.

The usbnet_generic_cdc_bind function in drivers/net/usb/cdc_ether.c in the Linux kernel through 4.13.11 allows local users to cause a denial of service (divide-by-zero error and system crash) or possibly have unspecified other impact via a crafted USB device.

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.

arch/x86/kernel/entry_32.S in the Linux kernel through 3.15.1 on 32-bit x86 platforms, when syscall auditing is enabled and the sep CPU feature flag is set, allows local users to cause a denial of service (OOPS and system crash) via an invalid syscall number, …

Multiple race conditions in ipc/shm.c in the Linux kernel before 3.12.2 allow local users to cause a denial of service (use-after-free and system crash) or possibly have unspecified other impact via a crafted application that uses shmctl IPC_RMID operations in…

Multiple buffer overflows in the hfsplus filesystem implementation in the Linux kernel before 3.3.5 allow local users to gain privileges via a crafted HFS plus filesystem, a related issue to CVE-2009-4020.

The KVM implementation in the Linux kernel before 3.3.4 does not properly manage the relationships between memory slots and the iommu, which allows guest OS users to cause a denial of service (memory leak and host OS crash) by leveraging administrative access …

In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_conntrack: fix crash due to removal of uninitialised entry A crash in conntrack was reported while trying to unlink the conntrack entry from the hash bucket list: [exceptio…

In the Linux kernel, the following vulnerability has been resolved: bpf: fix recursive lock when verdict program return SK_PASS When the stream_verdict program returns SK_PASS, it places the received skb into its own receive queue, but a recursive lock event…

In the Linux kernel, the following vulnerability has been resolved: xfrm: Fix input error path memory access When there is a misconfiguration of input state slow path KASAN report error. Fix this error. west login: [ 52.987278] eth1: renamed from veth11 [ …

In the Linux kernel, the following vulnerability has been resolved: dma: fix call order in dmam_free_coherent dmam_free_coherent() frees a DMA allocation, which makes the freed vaddr available for reuse, then calls devres_destroy() to remove and free the dat…

In the Linux kernel, the following vulnerability has been resolved: mptcp: fix data races on remote_id Similar to the previous patch, address the data race on remote_id, adding the suitable ONCE annotations.

An issue was discovered in the Linux kernel before 4.20.2. An out-of-bounds access exists in the function build_audio_procunit in the file sound/usb/mixer.c.

Buffer overflow in the mp_override_legacy_irq() function in arch/x86/kernel/acpi/boot.c in the Linux kernel through 3.2 allows local users to gain privileges via a crafted ACPI table.

The sock_setsockopt function in net/core/sock.c in the Linux kernel before 3.5 mishandles negative values of sk_sndbuf and sk_rcvbuf, which allows local users to cause a denial of service (memory corruption and system crash) or possibly have unspecified other …

The keyctl_read_key function in security/keys/keyctl.c in the Linux kernel before 4.3.4 does not properly use a semaphore, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impa…

Race condition in the IPC object implementation in the Linux kernel through 4.2.3 allows local users to gain privileges by triggering an ipc_addid call that leads to uid and gid comparisons against uninitialized data, related to msg.c, shm.c, and util.c.

The ext4_isize function in fs/ext4/ext4.h in the Linux kernel 2.6.27 before 2.6.27.19 and 2.6.28 before 2.6.28.7 uses the i_size_high structure member during operations on arbitrary types of files, which allows local users to cause a denial of service (CPU con…

The strnlen_user function in Linux kernel before 2.6.16 on IBM S/390 can return an incorrect value, which allows local users to cause a denial of service via unknown vectors.

The Linux Kernel before 2.6.15.5 allows local users to cause a denial of service (NFS client panic) via unknown attack vectors related to the use of O_DIRECT (direct I/O).

Buffer overflow in the ixj telephony card driver in Linux before 2.4.20 has unknown impact and attack vectors.

A flaw was found in the Netfilter subsystem in the Linux kernel. The nfnl_osf_add_callback function did not validate the user mode controlled opt_num field. This flaw allows a local privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds read, leading …

In the flush_tmregs_to_thread function in arch/powerpc/kernel/ptrace.c in the Linux kernel before 4.13.5, a guest kernel crash can be triggered from unprivileged userspace during a core dump on a POWER host due to a missing processor feature check and an erron…

A flaw was found in the hugetlb_mcopy_atomic_pte function in mm/hugetlb.c in the Linux kernel before 4.13.12. A lack of size check could cause a denial of service (BUG).

The KVM implementation in the Linux kernel before 3.3.6 allows host OS users to cause a denial of service (NULL pointer dereference and host OS crash) by making a KVM_CREATE_IRQCHIP ioctl call after a virtual CPU already exists.
