CVE-2019-19816 4 Canonical, Debian, Linux and 1 more 18 Ubuntu Linux, Debian Linux, Linux Kernel and 15 more 2023-01-19 9.3 HIGH 7.8 HIGH
In the Linux kernel 5.0.21, mounting a crafted btrfs filesystem image and performing some operations can cause slab-out-of-bounds write access in __btrfs_map_block in fs/btrfs/volumes.c, because a value of 1 for the number of data stripes is mishandled.
CVE-2018-16882 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2023-01-19 7.2 HIGH 8.8 HIGH
A use-after-free issue was found in the way the Linux kernel's KVM hypervisor processed posted interrupts when nested(=1) virtualization is enabled. In nested_get_vmcs12_pages(), in case of an error while processing posted interrupt address, it unmaps the 'pi_desc_page' without resetting 'pi_desc' descriptor address, which is later used in pi_test_and_clear_on(). A guest user/process could use this flaw to crash the host kernel resulting in DoS or potentially gain privileged access to a system. Kernel versions before 4.14.91 and before 4.19.13 are vulnerable.
CVE-2018-9363 4 Canonical, Debian, Google and 1 more 4 Ubuntu Linux, Debian Linux, Android and 1 more 2023-01-19 7.2 HIGH 8.4 HIGH
In the hidp_process_report in bluetooth, there is an integer overflow. This could lead to an out of bounds write with no additional execution privileges needed. User interaction is not needed for exploitation. Product: Android Versions: Android kernel Android ID: A-65853588 References: Upstream kernel.
CVE-2012-2135 3 Canonical, Debian, Python 3 Ubuntu Linux, Debian Linux, Python 2023-01-19 6.4 MEDIUM N/A
The utf-16 decoder in Python 3.1 through 3.3 does not update the aligned_end variable after calling the unicode_decode_call_errorhandler function, which allows remote attackers to obtain sensitive information (process memory) or cause a denial of service (memory corruption and crash) via unspecified vectors.
CVE-2017-11473 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2023-01-19 7.2 HIGH 7.8 HIGH
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.
CVE-2017-16995 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2023-01-19 7.2 HIGH 7.8 HIGH
The check_alu_op function in kernel/bpf/verifier.c in the Linux kernel through 4.4 allows local users to cause a denial of service (memory corruption) or possibly have unspecified other impact by leveraging incorrect sign extension.
CVE-2017-15868 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2023-01-19 7.2 HIGH 7.8 HIGH
The bnep_add_connection function in net/bluetooth/bnep/core.c in the Linux kernel before 3.19 does not ensure that an l2cap socket is available, which allows local users to gain privileges via a crafted application.
CVE-2017-16526 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2023-01-19 7.2 HIGH 7.8 HIGH
drivers/uwb/uwbd.c in the Linux kernel before 4.13.6 allows local users to cause a denial of service (general protection fault and system crash) or possibly have unspecified other impact via a crafted USB device.
CVE-2017-15115 4 Canonical, Debian, Linux and 1 more 4 Ubuntu Linux, Debian Linux, Linux Kernel and 1 more 2023-01-19 7.2 HIGH 7.8 HIGH
The sctp_do_peeloff function in net/sctp/socket.c in the Linux kernel before 4.14 does not check whether the intended netns is used in a peel-off action, which allows local users to cause a denial of service (use-after-free and system crash) or possibly have unspecified other impact via crafted system calls.
CVE-2017-17805 6 Canonical, Debian, Linux and 3 more 8 Ubuntu Linux, Debian Linux, Linux Kernel and 5 more 2023-01-19 7.2 HIGH 7.8 HIGH
The Salsa20 encryption algorithm in the Linux kernel before 4.14.8 does not correctly handle zero-length inputs, allowing a local attacker able to use the AF_ALG-based skcipher interface (CONFIG_CRYPTO_USER_API_SKCIPHER) to cause a denial of service (uninitialized-memory free and kernel crash) or have unspecified other impact by executing a crafted sequence of system calls that use the blkcipher_walk API. Both the generic implementation (crypto/salsa20_generic.c) and x86 implementation (arch/x86/crypto/salsa20_glue.c) of Salsa20 were vulnerable.
CVE-2018-6557 2 Base-files Project, Canonical 2 Base-files, Ubuntu Linux 2023-01-18 4.4 MEDIUM 7.0 HIGH
The MOTD update script in the base-files package in Ubuntu 18.04 LTS before 10.1ubuntu2.2, and Ubuntu 18.10 before 10.1ubuntu6 incorrectly handled temporary files. A local attacker could use this issue to cause a denial of service, or possibly escalate privileges if kernel symlink restrictions were disabled.
CVE-2013-1059 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2023-01-17 7.8 HIGH N/A
net/ceph/auth_none.c in the Linux kernel through 3.10 allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via an auth_reply message that triggers an attempted build_request operation.
CVE-2016-4565 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2023-01-17 7.2 HIGH 7.8 HIGH
The InfiniBand (aka IB) stack in the Linux kernel before 4.5.3 incorrectly relies on the write system call, which allows local users to cause a denial of service (kernel memory write operation) or possibly have unspecified other impact via a uAPI interface.
CVE-2016-1583 4 Canonical, Debian, Linux and 1 more 10 Ubuntu Linux, Debian Linux, Linux Kernel and 7 more 2023-01-17 7.2 HIGH 7.8 HIGH
The ecryptfs_privileged_open function in fs/ecryptfs/kthread.c in the Linux kernel before 4.6.3 allows local users to gain privileges or cause a denial of service (stack memory consumption) via vectors involving crafted mmap calls for /proc pathnames, leading to recursive pagefault handling.
CVE-2017-7645 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2023-01-17 7.8 HIGH 7.5 HIGH
The NFSv2/NFSv3 server in the nfsd subsystem in the Linux kernel through 4.10.11 allows remote attackers to cause a denial of service (system crash) via a long RPC reply, related to net/sunrpc/svc.c, fs/nfsd/nfs3xdr.c, and fs/nfsd/nfsxdr.c.
CVE-2019-15918 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2023-01-17 7.2 HIGH 7.8 HIGH
An issue was discovered in the Linux kernel before 5.0.10. SMB2_negotiate in fs/cifs/smb2pdu.c has an out-of-bounds read because data structures are incompletely updated after a change from smb30 to smb21.
