| CVE-2018-1120 | Low | 0.22 | 2.8 | 0.07 | Jun 20, 2018 | A flaw was found affecting the Linux kernel before version 4.17. By mmap()ing a FUSE-backed file onto a process's memory containing command line arguments (or environment strings), an attacker can cause utilities from psutils or procps (such as ps, w) or any other program which… | ||
| CVE-2018-1123 | Low | 0.22 | 3.9 | 0.09 | May 23, 2018 | procps-ng before version 3.3.15 is vulnerable to a denial of service in ps via mmap buffer overflow. Inbuilt protection in ps maps a guard page at the end of the overflowed buffer, ensuring that the impact of this flaw is limited to a crash (temporary denial of service). | ||
| CVE-2018-2771 | Med | 0.22 | 4.4 | 0.04 | Apr 19, 2018 | Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Server: Locking). Supported versions that are affected are 5.5.59 and prior, 5.6.39 and prior and 5.7.21 and prior. Difficult to exploit vulnerability allows high privileged attacker with network access… | ||
| CVE-2026-47337 | Low | 0.21 | 3.3 | 0.00 | May 28, 2026 | Ubuntu Linux 6.8, 6.17 and 7.0 contain SAUCE patches with a possible NULL pointer dereference in the handling of AF_INET/AF_INET6 socket mediation. The bug can be triggered by an unprivileged local user. This can lead to a kernel oops. | ||
| CVE-2026-47336 | Low | 0.21 | 3.3 | 0.00 | May 28, 2026 | Ubuntu Linux 6.8 contains SAUCE patches with a possible use of an uninitialized variable in AppArmor AF_INET/AF_INET6 socket mediation code. The bug can be triggered by an unprivileged local user and could result in incorrect fine-grained mediation of network sockets. | ||
| CVE-2026-47330 | Low | 0.21 | 3.3 | 0.00 | May 28, 2026 | Ubuntu Linux 6.8, 7.17 and 7.0 contain AppArmor SAUCE patches which can, under certain circumstances, use an uninitialized variable in notification handling code. The bug can be triggered by an unprivileged local user and can result in the incorrect caching of AppArmor… | ||
| CVE-2026-47329 | Low | 0.21 | 3.3 | 0.00 | May 28, 2026 | Ubuntu Linux 6.8, 6.17 and 7.0 contain SAUCE patches which fail to validate invalid sizes of the name field in AppAmor notification responses. The bug can be triggered by an unprivileged local user and could result in handling of crafted responses. | ||
| CVE-2026-47327 | Low | 0.21 | 3.3 | 0.00 | May 28, 2026 | Ubuntu Linux 6.8, 6.17 and 7.0 contain SAUCE patches with a possible NULL pointer dereference in the handling of AppArmor notifications. The bug can be triggered by an unprivileged local user. This can lead to a kernel oops. | ||
| CVE-2020-16121 | Low | 0.21 | 3.3 | 0.00 | Nov 7, 2020 | PackageKit provided detailed error messages to unprivileged callers that exposed information about file presence and mimetype of files that the user would be unable to determine on its own. | ||
| CVE-2020-14378 | Low | 0.21 | 3.3 | 0.00 | Sep 30, 2020 | An integer underflow in dpdk versions before 18.11.10 and before 19.11.5 in the `move_desc` function can lead to large amounts of CPU cycles being eaten up in a long running loop. An attacker could cause `move_desc` to get stuck in a 4,294,967,295-count iteration loop. Depending… | ||
| CVE-2020-14415 | Low | 0.21 | 3.3 | 0.00 | Aug 27, 2020 | oss_write in audio/ossaudio.c in QEMU before 5.0.0 mishandles a buffer position. | ||
| CVE-2020-10732 | Low | 0.21 | 3.3 | 0.01 | Jun 12, 2020 | A flaw was found in the Linux kernel's implementation of Userspace core dumps. This flaw allows an attacker with a local account to crash a trivial program and exfiltrate private kernel data. | ||
| CVE-2020-13362 | Low | 0.21 | 3.2 | 0.00 | May 28, 2020 | In QEMU 5.0.0 and earlier, megasas_lookup_frame in hw/scsi/megasas.c has an out-of-bounds read via a crafted reply_queue_head field from a guest OS user. | ||
| CVE-2020-11931 | Low | 0.21 | 3.3 | 0.00 | May 15, 2020 | An Ubuntu-specific modification to Pulseaudio to provide security mediation for Snap-packaged applications was found to have a bypass of intended access restriction for snaps which plugs any of pulseaudio, audio-playback or audio-record via unloading the pulseaudio snap policy… | ||
| CVE-2019-11485 | Low | 0.21 | 3.3 | 0.00 | Feb 8, 2020 | Sander Bos discovered Apport's lock file was in a world-writable directory which allowed all users to prevent crash handling. | ||
| CVE-2019-17055 | Low | 0.21 | 3.3 | 0.01 | Oct 1, 2019 | base_sock_create in drivers/isdn/mISDN/socket.c in the AF_ISDN network module in the Linux kernel through 5.3.2 does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka CID-b91ee4aa2a21. | ||
| CVE-2019-16680 | Med | 0.21 | 4.3 | 0.02 | Sep 21, 2019 | An issue was discovered in GNOME file-roller before 3.29.91. It allows a single ./../ path traversal via a filename contained in a TAR archive, possibly overwriting a file during extraction. | ||
| CVE-2019-11884 | Low | 0.21 | 3.3 | 0.01 | May 10, 2019 | The do_hidp_sock_ioctl function in net/bluetooth/hidp/sock.c in the Linux kernel before 5.0.15 allows a local user to obtain potentially sensitive information from kernel stack memory via a HIDPCONNADD command, because a name field may not end with a '\0' character. | ||
| CVE-2019-3823 | Med | 0.21 | 4.3 | 0.04 | Feb 6, 2019 | libcurl versions from 7.34.0 to before 7.64.0 are vulnerable to a heap out-of-bounds read in the code handling the end-of-response for SMTP. If the buffer passed to `smtp_endofresp()` isn't NUL terminated and contains no character ending the parsed number, and `len` is set to 5,… | ||
| CVE-2018-6559 | Low | 0.21 | 3.3 | 0.01 | Oct 26, 2018 | The Linux kernel, as used in Ubuntu 18.04 LTS and Ubuntu 18.10, allows local users to obtain names of files in which they would not normally be able to access via an overlayfs mount inside of a user namespace. |
