CVE-2019-9506 [HIGH] CWE-310 CVE-2019-9506: The Bluetooth BR/EDR specification up to and including version 5.1 permits sufficiently low encrypti The Bluetooth BR/EDR specification up to and including version 5.1 permits sufficiently low encryption key length and does not prevent an attacker from influencing the key length negotiation. This allows practical brute-force attacks (aka "KNOB") that can decrypt traffic and inject arbitrary ciphertext without the victim noticing.

CVE-2009-0846 [CRITICAL] CWE-824 CVE-2009-0846: The asn1_decode_generaltime function in lib/krb5/asn.1/asn1_decode.c in the ASN.1 GeneralizedTime de The asn1_decode_generaltime function in lib/krb5/asn.1/asn1_decode.c in the ASN.1 GeneralizedTime decoder in MIT Kerberos 5 (aka krb5) before 1.6.4 allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via vectors involving an invalid DER encoding that triggers a free of an uninitialized pointer.

CVE-2022-1708 [HIGH] CWE-400 CVE-2022-1708: A vulnerability was found in CRI-O that causes memory or disk space exhaustion on the node for anyon A vulnerability was found in CRI-O that causes memory or disk space exhaustion on the node for anyone with access to the Kube API. The ExecSync request runs commands in a container and logs the output of the command. This output is then read by CRI-O after command execution, and it is read in a manner where the entire file corresponding to the output of

CVE-2017-5460 [CRITICAL] CWE-416 CVE-2017-5460: A use-after-free vulnerability in frame selection triggered by a combination of malicious script con A use-after-free vulnerability in frame selection triggered by a combination of malicious script content and key presses by a user. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 52.1, Firefox ESR < 45.9, Firefox ESR < 52.1, and Firefox < 53.

CVE-2023-0179 [HIGH] CWE-190 CVE-2023-0179: A buffer overflow vulnerability was found in the Netfilter subsystem in the Linux Kernel. This issue A buffer overflow vulnerability was found in the Netfilter subsystem in the Linux Kernel. This issue could allow the leakage of both stack and heap addresses, and potentially allow Local Privilege Escalation to the root user via arbitrary code execution.

CVE-2023-39191 [HIGH] CWE-20 CVE-2023-39191: An improper input validation flaw was found in the eBPF subsystem in the Linux kernel. The issue occ An improper input validation flaw was found in the eBPF subsystem in the Linux kernel. The issue occurs due to a lack of proper validation of dynamic pointers within user-supplied eBPF programs prior to executing them. This may allow an attacker with CAP_BPF privileges to escalate privileges and execute arbitrary code in the context of the kernel.

CVE-2024-0553 [HIGH] CVE-2024-0553: A vulnerability was found in GnuTLS. The response times to malformed ciphertexts in RSA-PSK ClientKe A vulnerability was found in GnuTLS. The response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from the response times of ciphertexts with correct PKCS#1 v1.5 padding. This issue may allow a remote attacker to perform a timing side-channel attack in the RSA-PSK key exchange, potentially leading to the leakage of sensitive data. CVE-2024-05

CVE-2025-26595 [HIGH] CWE-121 CVE-2025-26595: A buffer overflow flaw was found in X.Org and Xwayland. The code in XkbVModMaskText() allocates a fi A buffer overflow flaw was found in X.Org and Xwayland. The code in XkbVModMaskText() allocates a fixed-sized buffer on the stack and copies the names of the virtual modifiers to that buffer. The code fails to check the bounds of the buffer and would copy the data regardless of the size.

CVE-2023-0361 [HIGH] CWE-203 CVE-2023-0361: A timing side-channel in the handling of RSA ClientKeyExchange messages was discovered in GnuTLS. Th A timing side-channel in the handling of RSA ClientKeyExchange messages was discovered in GnuTLS. This side-channel can be sufficient to recover the key encrypted in the RSA ciphertext across a network in a Bleichenbacher style attack. To achieve a successful decryption the attacker would need to send a large amount of specially crafted messages to the

CVE-2025-26598 [HIGH] CWE-787 CVE-2025-26598: An out-of-bounds write flaw was found in X.Org and Xwayland. The function GetBarrierDevice() searche An out-of-bounds write flaw was found in X.Org and Xwayland. The function GetBarrierDevice() searches for the pointer device based on its device ID and returns the matching value, or supposedly NULL, if no match was found. However, the code will return the last element of the list if no matching device ID is found, which can lead to out-of-bounds memo

CVE-2022-27650 [HIGH] CWE-276 CVE-2022-27650: A flaw was found in crun where containers were incorrectly started with non-empty default permission A flaw was found in crun where containers were incorrectly started with non-empty default permissions. A vulnerability was found in Moby (Docker Engine) where containers were started incorrectly with non-empty inheritable Linux process capabilities. This flaw allows an attacker with access to programs with inheritable file capabilities to elevate thos

CVE-2025-5914 [HIGH] CWE-190 CVE-2025-5914: A vulnerability has been identified in the libarchive library, specifically within the archive_read_ A vulnerability has been identified in the libarchive library, specifically within the archive_read_format_rar_seek_data() function. This flaw involves an integer overflow that can ultimately lead to a double-free condition. Exploiting a double-free vulnerability can result in memory corruption, enabling an attacker to execute arbitrary code or cause a

CVE-2023-3899 [HIGH] CWE-285 CVE-2023-3899: A vulnerability was found in subscription-manager that allows local privilege escalation due to inad A vulnerability was found in subscription-manager that allows local privilege escalation due to inadequate authorization. The D-Bus interface com.redhat.RHSM1 exposes a significant number of methods to all users that could change the state of the registration. By using the com.redhat.RHSM1.Config.SetAll() method, a low-privileged local user could tamper

CVE-2018-14648 [HIGH] CWE-400 CVE-2018-14648: A flaw was found in 389 Directory Server. A specially crafted search query could lead to excessive C A flaw was found in 389 Directory Server. A specially crafted search query could lead to excessive CPU consumption in the do_search() function. An unauthenticated attacker could use this flaw to provoke a denial of service.

CVE-2024-12086 [MEDIUM] CWE-390 CVE-2024-12086: A flaw was found in rsync. It could allow a server to enumerate the contents of an arbitrary file fr A flaw was found in rsync. It could allow a server to enumerate the contents of an arbitrary file from the client's machine. This issue occurs when files are being copied from a client to a server. During this process, the rsync server will send checksums of local data to the client to compare with in order to determine what data needs to be sent to

CVE-2025-62231 [HIGH] CWE-190 CVE-2025-62231: A flaw was identified in the X.Org X server’s X Keyboard (Xkb) extension where improper bounds check A flaw was identified in the X.Org X server’s X Keyboard (Xkb) extension where improper bounds checking in the XkbSetCompatMap() function can cause an unsigned short overflow. If an attacker sends specially crafted input data, the value calculation may overflow, leading to memory corruption or a crash.

CVE-2020-6851 [HIGH] CWE-787 CVE-2020-6851: OpenJPEG through 2.3.1 has a heap-based buffer overflow in opj_t1_clbl_decode_processor in openjp2/t OpenJPEG through 2.3.1 has a heap-based buffer overflow in opj_t1_clbl_decode_processor in openjp2/t1.c because of lack of opj_j2k_update_image_dimensions validation.

CVE-2019-17596 [HIGH] CWE-436 CVE-2019-17596: Go before 1.12.11 and 1.3.x before 1.13.2 can panic upon an attempt to process network traffic conta Go before 1.12.11 and 1.3.x before 1.13.2 can panic upon an attempt to process network traffic containing an invalid DSA public key. There are several attack scenarios, such as traffic from a client to a server that verifies client certificates.
