CVE-2021-3697 [HIGH] CWE-787 CVE-2021-3697: A crafted JPEG image may lead the JPEG reader to underflow its data pointer, allowing user-controlle A crafted JPEG image may lead the JPEG reader to underflow its data pointer, allowing user-controlled data to be written in heap. To a successful to be performed the attacker needs to perform some triage over the heap layout and craft an image with a malicious format and payload. This vulnerability can lead to data corruption and eventual code execution

CVE-2024-6505 [MEDIUM] CWE-125 CVE-2024-6505: A flaw was found in the virtio-net device in QEMU. When enabling the RSS feature on the virtio-net n A flaw was found in the virtio-net device in QEMU. When enabling the RSS feature on the virtio-net network card, the indirections_table data within RSS becomes controllable. Setting excessively large values may cause an index out-of-bounds issue, potentially resulting in heap overflow access. This flaw allows a privileged user in the guest to crash th

CVE-2021-3667 [MEDIUM] CWE-667 CVE-2021-3667: An improper locking issue was found in the virStoragePoolLookupByTargetPath API of libvirt. It occur An improper locking issue was found in the virStoragePoolLookupByTargetPath API of libvirt. It occurs in the storagePoolLookupByTargetPath function where a locked virStoragePoolObj object is not properly released on ACL permission failure. Clients connecting to the read-write socket with limited ACL permissions could use this flaw to acquire the lock

CVE-2020-15707 [MEDIUM] CWE-362 CVE-2020-15707: Integer overflows were discovered in the functions grub_cmd_initrd and grub_initrd_init in the efili Integer overflows were discovered in the functions grub_cmd_initrd and grub_initrd_init in the efilinux component of GRUB2, as shipped in Debian, Red Hat, and Ubuntu (the functionality is not included in GRUB2 upstream), leading to a heap-based buffer overflow. These could be triggered by an extremely large number of arguments to the initrd command

CVE-2023-1192 [MEDIUM] CWE-416 CVE-2023-1192: A use-after-free flaw was found in smb2_is_status_io_timeout() in CIFS in the Linux Kernel. After CI A use-after-free flaw was found in smb2_is_status_io_timeout() in CIFS in the Linux Kernel. After CIFS transfers response data to a system call, there are still local variable points to the memory region, and if the system call frees it faster than CIFS uses it, CIFS will access a free memory region, leading to a denial of service.

CVE-2025-7519 [MEDIUM] CWE-787 CVE-2025-7519: A flaw was found in polkit. When processing an XML policy with 32 or more nested elements in depth, A flaw was found in polkit. When processing an XML policy with 32 or more nested elements in depth, an out-of-bounds write can be triggered. This issue can lead to a crash or other unexpected behavior, and arbitrary code execution is not discarded. To exploit this flaw, a high-privilege account is needed as it's required to place the malicious policy f

CVE-2025-14512 [MEDIUM] CWE-190 CVE-2025-14512: A flaw was found in glib. This vulnerability allows a heap buffer overflow and denial-of-service (Do A flaw was found in glib. This vulnerability allows a heap buffer overflow and denial-of-service (DoS) via an integer overflow in GLib's GIO (GLib Input/Output) escape_byte_string() function when processing malicious file or remote filesystem attribute values.

CVE-2020-1726 [MEDIUM] CWE-552 CVE-2020-1726: A flaw was discovered in Podman where it incorrectly allows containers when created to overwrite exi A flaw was discovered in Podman where it incorrectly allows containers when created to overwrite existing files in volumes, even if they are mounted as read-only. When a user runs a malicious container or a container based on a malicious image with an attached volume that is used for the first time, it is possible to trigger the flaw and overwrite fil

CVE-2026-9149 [MEDIUM] CWE-122 CVE-2026-9149: A flaw was found in libsolv. This heap buffer overflow vulnerability occurs when a victim processes A flaw was found in libsolv. This heap buffer overflow vulnerability occurs when a victim processes a specially crafted `.solv` file containing negative size values in the `repo_add_solv` function. This leads to an undersized memory allocation and a subsequent out-of-bounds write. An attacker could exploit this to cause a denial of service (DoS).

CVE-2026-11611 [MEDIUM] CWE-400 CVE-2026-11611: A flaw was found in 389 Directory Server. The Content Synchronization persistent search plugin allow A flaw was found in 389 Directory Server. The Content Synchronization persistent search plugin allows unbounded memory growth when an authenticated client stops reading sync responses, enabling denial of service. Additional race conditions in plugin thread lifecycle can cause crashes during connection teardown or shutdown.

CVE-2018-1049 [MEDIUM] CWE-362 CVE-2018-1049: In systemd prior to 234 a race condition exists between .mount and .automount units such that automo In systemd prior to 234 a race condition exists between .mount and .automount units such that automount requests from kernel may not be serviced by systemd resulting in kernel holding the mountpoint and any processes that try to use said mount will hang. A race condition like this may lead to denial of service, until mount points are unmounted.

CVE-2017-5449 [HIGH] CWE-20 CVE-2017-5449: A possibly exploitable crash triggered during layout and manipulation of bidirectional unicode text A possibly exploitable crash triggered during layout and manipulation of bidirectional unicode text in concert with CSS animations.
