CVE-2023-0361 5 Debian, Fedoraproject, Gnu and 2 more 8 Debian Linux, Fedora, Gnutls and 5 more 2026-10-14 7.4 High
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 vulnerable server. By recovering the secret from the ClientKeyExchange message, the attacker would be able to decrypt the application data exchanged over that connection.
CVE-2026-97782 1 Microsoft 1 Sharepoint Server 2026-10-14 6.8 Medium
Observable discrepancy in Microsoft Office SharePoint allows an authorized attacker to perform tampering over a network.
CVE-2026-106351 2 Apple, Google 2 Iphone Os, Chrome 2026-10-14 5.3 Medium
Observable discrepancy in Safebrowsing in Google Chrome on on iOS prior to 155.0.8059.39 allowed a remote attacker who had compromised the renderer process to obtain sensitive information via a crafted HTML page. (Chromium security severity: Medium)
CVE-2026-110141 1 Google 1 Chrome 2026-10-14 3.1 Low
Observable discrepancy in Media in Google Chrome prior to 155.0.8059.79 allowed a remote attacker to leak cross-origin data via a crafted HTML page. (Chromium security severity: High)
CVE-2022-4304 3 Openssl, Redhat, Stormshield 8 Openssl, Enterprise Linux, Jboss Core Services and 5 more 2026-10-14 5.9 Medium
A timing based side channel exists in the OpenSSL RSA Decryption implementation which could be sufficient to recover a plaintext across a network in a Bleichenbacher style attack. To achieve a successful decryption an attacker would have to be able to send a very large number of trial messages for decryption. The vulnerability affects all RSA padding modes: PKCS#1 v1.5, RSA-OEAP and RSASVE. For example, in a TLS connection, RSA is commonly used by a client to send an encrypted pre-master secret to the server. An attacker that had observed a genuine connection between a client and a server could use this flaw to send trial messages to the server and record the time taken to process them. After a sufficiently large number of messages the attacker could recover the pre-master secret used for the original connection and thus be able to decrypt the application data sent over that connection.
CVE-2021-33560 5 Debian, Fedoraproject, Gnupg and 2 more 9 Debian Linux, Fedora, Libgcrypt and 6 more 2026-10-14 7.5 High
Libgcrypt before 1.8.8 and 1.9.x before 1.9.3 mishandles ElGamal encryption because it lacks exponent blinding to address a side-channel attack against mpi_powm, and the window size is not chosen appropriately. This, for example, affects use of ElGamal in OpenPGP.
CVE-2020-14145 3 Netapp, Openbsd, Redhat 11 Active Iq Unified Manager, Aff A700s, Aff A700s Firmware and 8 more 2026-10-14 5.9 Medium
The client side in OpenSSH 5.7 through 8.4 has an Observable Discrepancy leading to an information leak in the algorithm negotiation. This allows man-in-the-middle attackers to target initial connection attempts (where no host key for the server has been cached by the client). NOTE: some reports state that 8.5 and 8.6 are also affected.
CVE-2019-13627 5 Canonical, Debian, Libgcrypt20 Project and 2 more 5 Ubuntu Linux, Debian Linux, Libgcrypt20 and 2 more 2026-10-14 6.3 Medium
It was discovered that there was a ECDSA timing attack in the libgcrypt20 cryptographic library. Version affected: 1.8.4-5, 1.7.6-2+deb9u3, and 1.6.3-2+deb8u4. Versions fixed: 1.8.5-2 and 1.6.3-2+deb8u7.
CVE-2018-0495 5 Canonical, Debian, Gnupg and 2 more 14 Ubuntu Linux, Debian Linux, Libgcrypt and 11 more 2026-10-14 N/A
Libgcrypt before 1.7.10 and 1.8.x before 1.8.3 allows a memory-cache side-channel attack on ECDSA signatures that can be mitigated through the use of blinding during the signing process in the _gcry_ecc_ecdsa_sign function in cipher/ecc-ecdsa.c, aka the Return Of the Hidden Number Problem or ROHNP. To discover an ECDSA key, the attacker needs access to either the local machine or a different virtual machine on the same physical host.
CVE-2026-88834 2 Busybox, Redhat 2 Busybox, Hummingbird 2026-10-13 3.7 Low
A flaw was found in BusyBox's httpd web server. When configured with system password authentication, a user existence oracle may exist in certain build configurations. An attacker could distinguish existing from non-existing usernames by observing authentication failure behavior. Impact is limited to username enumeration and requires non-default compile options or uncommon password file states; default BusyBox builds with shadow password support are not affected.
CVE-2026-106506 2 Backstage, Linuxfoundation 4 Backstage, Plugin-scaffolder-backend, Backstage and 1 more 2026-10-09 5.3 Medium
Backstage is an open framework for building developer portals. Prior to 4.1.0, the @backstage/plugin-scaffolder-backend package is affected by improper input validation in scaffolder task list ordering. An authenticated Backstage user with permission to create and read relevant scaffolder tasks may be able to infer confidential task data under specific conditions. Successful exploitation requires retained task secrets, visibility of a target task, knowledge of the secret structure, and repeated requests. This issue is fixed in version 4.1.0.
CVE-2016-0762 6 Apache, Canonical, Debian and 3 more 16 Tomcat, Ubuntu Linux, Debian Linux and 13 more 2026-10-08 5.9 Medium
The Realm implementations in Apache Tomcat versions 9.0.0.M1 to 9.0.0.M9, 8.5.0 to 8.5.4, 8.0.0.RC1 to 8.0.36, 7.0.0 to 7.0.70 and 6.0.0 to 6.0.45 did not process the supplied password if the supplied user name did not exist. This made a timing attack possible to determine valid user names. Note that the default configuration includes the LockOutRealm which makes exploitation of this vulnerability harder.
CVE-2021-35477 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2026-10-08 5.5 Medium
In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from kernel memory via a Speculative Store Bypass side-channel attack because a certain preempting store operation does not necessarily occur before a store operation that has an attacker-controlled value.
CVE-2021-34556 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2026-10-08 5.5 Medium
In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from kernel memory via a Speculative Store Bypass side-channel attack because the protection mechanism neglects the possibility of uninitialized memory locations on the BPF stack.
CVE-2020-27170 5 Canonical, Debian, Fedoraproject and 2 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2026-10-08 4.7 Medium
An issue was discovered in the Linux kernel before 5.11.8. kernel/bpf/verifier.c performs undesirable out-of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre mitigations and obtain sensitive information from kernel memory, aka CID-f232326f6966. This affects pointer types that do not define a ptr_limit.
CVE-2024-9398 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2026-10-08 5.3 Medium
By checking the result of calls to `window.open` with specifically set protocol handlers, an attacker could determine if the application which implements that protocol handler is installed. This vulnerability affects Firefox < 131, Firefox ESR < 128.3, Thunderbird < 128.3, and Thunderbird < 131.
CVE-2026-11795 1 Softtr Informatics Technology Trading Limited Company 1 E-commerce Pack 2026-10-08 5.3 Medium
Observable discrepancy vulnerability in Softtr Informatics Trading Limited Company E-Commerce Pack allows Account Footprinting. This issue affects E-Commerce Pack: before 5.03.01.54.
CVE-2026-106210 1 Google 1 Chrome 2026-10-08 3.1 Low
Observable discrepancy in Scroll in Google Chrome prior to 155.0.8059.39 allowed a remote attacker to obtain cross-origin data via a crafted Chrome extension. (Chromium security severity: Medium)
CVE-2026-106180 1 Google 1 Chrome 2026-10-08 3.1 Low
Observable discrepancy in Animation in Google Chrome prior to 155.0.8059.39 allowed a remote attacker to potentially obtain cross-origin data via a crafted HTML page. (Chromium security severity: Medium)
