Ubuntu 16.04 LTS / 18.04 LTS : Linux kernel vulnerabilities (USN-4345-1)

The remote Ubuntu 16.04 LTS / 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4345-1 advisory. Al Viro discovered that the Linux kernel for s390x systems did not properly perform page table upgrades for kernel sections that use secondar...

CVE-2019-15877

In FreeBSD 12.1-STABLE before r356606 and 12.1-RELEASE before 12.1-RELEASE-p3, driver specific ioctl command handlers in the ixl network driver failed to check whether the caller has sufficient privileges allowing unprivileged users to trigger updates to the device's non-volatile memory...

CVE-2019-15791

In shiftfs, a non-upstream patch to the Linux kernel included in the Ubuntu 5.0 and 5.3 kernel series, shiftfsbtrfsioctlfdreplace installs an fd referencing a file from the lower filesystem without taking an additional reference to that file. After the btrfs ioctl completes this fd is closed, whi...

CVE-2019-15791 Reference count underflow in shiftfs

In shiftfs, a non-upstream patch to the Linux kernel included in the Ubuntu 5.0 and 5.3 kernel series, shiftfsbtrfsioctlfdreplace installs an fd referencing a file from the lower filesystem without taking an additional reference to that file. After the btrfs ioctl completes this fd is closed, whi...

Memory corruption

When issuing IOCTL calls to ION, Memory leak can occur due to failure in unassign pages under certain conditions in Snapdragon Auto, Snapdragon Compute, Snapdragon Consumer Electronics Connectivity, Snapdragon Consumer IOT, Snapdragon Industrial IOT, Snapdragon Mobile, Snapdragon Voice & Music,...

CVE-2019-10547

CVE-2019-10547 describes a memory leak in IOCTL handling for ION on Snapdragon platforms (APQ8009, APQ8053, APQ8096AU, etc.). The root cause is failure to unassign pages under certain conditions, affecting a wide range of Snapdragon variants (Auto, Compute, NR/IoT, Wearables, and more). CVSS metr...

Information Disclosure

kernel is vulnerable to information disclosure. The cxgbextensionioctl function in drivers/net/cxgb3/cxgb3main.c does not properly initialize a certain structure member, which allows local users to obtain potentially confidential information from kernel stack memory via a CHELSIOGETQSETNUM ioctl...

Denial Of Service (DoS)

The kernel is vulnerable to denial of service DoS. A flaw in the Linux kernel's packet writing driver could be triggered via the PKTCTRLCMDSTATUS IOCTL request, possibly allowing a local, unprivileged user with access to "/dev/pktcdvd/control" to cause an information leak. Note: By default, only...

Information Disclosure

kernel is vulnerable to information disclosure. A flaw was found in the handling of the SWAPEXT IOCTL in the Linux kernel XFS file system implementation. A local user could use this flaw to read write-only files, that they do not own, on an XFS file system. This could lead to unintended informati...

Denial Of Service (DoS)

kernel is vulnerable to denial of service. A NULL pointer dereference flaws were found in the r128 driver in the Linux kernel. Checks to test if the Concurrent Command Engine state was initialized were missing in private IOCTL functions. An attacker could use these flaws to cause a local denial o...

Information Disclosure

kernel-rt is vulnerable to information disclosure. The vulnerability exists as missing boundary checks were reported in the Linux kernel SCTP implementation. This could, potentially, cause information disclosure via a specially crafted SCTPHMACIDENT IOCTL request...

bpftool, kernel, perf, python security update

CentOS Errata and Security Advisory CESA-2020:1016 An update for kernel is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity...

CVE-2019-11884

A flaw was found in the Linux kernel's implementation of the Bluetooth Human Interface Device Protocol HIDP. A local attacker with access permissions to the Bluetooth device can issue an IOCTL which will trigger the dohidpsockioctl function in net/bluetooth/hidp/sock.c.c. This function can leak...
