[SECURITY] Fedora 44 Update: opencryptoki-3.26.0-3.fc44

Opencryptoki implements the PKCS11 specification v3.0 and partially v3.1 for a set of cryptographic hardware, such as IBM 4767, 4768, 4769 and 4770 crypto cards, and the Trusted Platform Module TPM chip. Opencryptoki also brings a software token implementation that can be used without any cryptog...

PT-2026-42602

Impact A logic flaw in BlockInclusionProof::is block proven causes the function to return true without performing any cryptographic verification when get interlink hops yields an empty hop list. This occurs when the target block is at the election block position immediately preceding the election...

kernel: "Fragnesia" is a variant of Dirty Frag vulnerability in the ESP/XFRM leading to Local Privilege Escalation (LPE) vulnerability in the Linux kernel

A flaw was found in the Linux kernel's XFRM ESP-in-TCP subsystem. Unsafe in-place cryptographic processing allows a low-privileged local attacker to write arbitrary bytes into the page cache of read-only files, including sensitive system files. An attacker can exploit this to overwrite privileged...

crypto/tls: crypto/tls: Incorrect certificate validation during TLS session resumption

A flaw was found in the crypto/tls component. This vulnerability occurs during Transport Layer Security TLS session resumption when certificate authority CA settings are modified between the initial and resumed handshakes. An attacker could exploit this to bypass certificate validation, allowing ...

kernel: "Dirty Frag" ESP XFRM variant is a new universal Local Privilege Escalation (LPE) vulnerability in the Linux kernel

A flaw was found in the Linux kernel's xfrm-ESP and RxRPC subsystems. Unsafe in-place cryptographic processing of shared socket buffer fragments allows a low-privileged local attacker to corrupt page-cache contents of readable files, including sensitive system files, and gain root privileges. The...

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: crypto: seqiv – Properly handles the EBUSY error. Since seqiv only handles the special return value of EINPROGERSS, it means that in all other cases, it will free the data related to the request. However, since the caller of seqi...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

A null pointer dereference flaw was discovered in the Linux kernel API for the cryptographic algorithm scatterwalk functionality. This issue occurs when a user constructs a malicious packet with specific socket configurations, which could allow a local user to crash the system or escalate their...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: mac80211: fixed a use-after-free in CCMP/GCMP RX. When PN checking is performed in mac80211, for fragmentation purposes, we need to copy the PN into the RX struct so that it can be used later for comparison. This is reflected in...

Astra Linux – Vulnerability in NTP

In NTP versions 4.2.8, 4.2.8p15, and 4.3.x, before 4.3.101, remote attackers could cause a denial of service memory consumption by sending packets. This occurs because memory is not released in situations where a CMAC key is used and associated with a CMAC algorithm in the ntp.keys file...

Astra Linux – Vulnerability in krb5

A vulnerability in the MIT Kerberos implementation allows for GSSAPI-protected messages that use RC4-HMAC-MD5 to be spoofed, due to weaknesses in the MD5 checksum design. If RC4 is preferred over stronger encryption methods, an attacker could exploit MD5 collisions to forge message integrity code...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: crypto: caam – fix DMA corruption on long hmac keys When a key longer than the block size is provided, it is copied and then hashed into the actual key. The memory allocated for the copy needs to be rounded to the DMA cache...

Astra Linux – Vulnerability in opensc

A flaw was discovered in OpenSC packages that could allow for a potential PIN bypass. When a token/card is authenticated by one process, it can perform cryptographic operations in other processes when an empty zero-length PIN is passed. This issue poses a security risk, especially for OS...

Astra Linux – Vulnerability in libgcrypt20

The ElGamal implementation in Libgcrypt before version 1.9.4 allows plaintext recovery. This occurs because, during interaction between two cryptographic libraries, a dangerous combination of elements arises—specifically, the prime number defined by the receiver’s public key, the generator define...

PT-2026-42270

Name of the Vulnerable Software and Affected Versions Crypt::SaltedHash versions prior to 0.10 Description Crypt::SaltedHash for Perl generates insecure random values for salts because it utilizes the built-in rand function, which is predictable and unsuitable for cryptographic purposes...
