Insufficient Verification of Data Authenticity

Overview Affected versions of this package are vulnerable to Insufficient Verification of Data Authenticity through the misleadingly named HmacSha256.hash function. An attacker can bypass message authentication by exploiting the use of an unkeyed digest where a keyed HMAC was expected. This is on...

Oj: Use-After-Free in Oj::Parser array_class/hash_class GC Marking

Summary Oj::Parser in usual mode does not mark arrayclass and hashclass references during garbage collection. If GC runs after the class is assigned but before a parse, the class object is reclaimed, leaving the parser holding a dangling VALUE. The subsequent parse call dereferences the freed...

Use After Free

Overview Affected versions of this package are vulnerable to Use After Free in the parsermark. An attacker can cause a segmentation fault and potentially crash the application by triggering garbage collection after assigning a custom class to arrayclass or hashclass and before parsing, leading to...

kernel: RDMA/mana: Validate rx_hash_key_len

A flaw was found in the Linux kernel's RDMA/mana component. A local user could exploit this vulnerability by providing an invalid rxhashkeylen value through a user-space API uAPI structure. This invalid value is then used in a memcpy operation without proper bounds checking, allowing the user to...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: RDMA/mana: Validating rxhashkeylen Sashiko points out that rxhashkeylen comes from a uAPI structure and is blindly passed to memcpy, allowing the user space to corrupt kernel memory. A bounds check is performed to prevent memcpy...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: bpf: Requires the map to be frozen before calculating the map hash Currently, bpfmapgetinfobyfd calculates and caches the hash of the map, regardless of whether the map is frozen or not. This leads to a TOCTOU bug, where user spa...

PT-2026-53789

Impact The HmacSha256 class contained two functions: - hashpayload — a plain unkeyed SHA-256 digest. The Hmac prefix in the class name was misleading; this function has no key parameter, so it could never have been an HMAC. - hmacSHA256key, data — a properly keyed HMAC-SHA256. A reader who didn't...

Name of the Vulnerable Software and Affected Versions Oj versions prior to 3.17.2 Description Oj::Parser in usual mode fails to mark array class and hash class references during garbage collection GC, resulting in a Use-After-Free condition. If the GC executes after the class is assigned but befo...

Oj- Use-After-Free in 'Oj::Parser' array_class/hash_class GC Marking

Oj - Use-After-Free in 'Oj::Parser' SAJ Long Key Callback

Summary Oj::Parser in SAJ mode does not protect cached object keys ≥ 35 bytes from garbage collection. A Ruby callback that triggers GC inside hashend can cause the key string to be reclaimed while the C parser still holds a pointer to it. The subsequent access to the freed string VALUE results i...

CVE-2026-9692

Mojolicious::Sessions::Storable versions through 0.05 for Perl generate session ids insecurely. The default session id generator returns a SHA-1 hash seeded with the built-in rand function, the epoch time, the heap address of an anonymous hash, and the PID. These are predictable or low-entropy...

Siemens RuggedCom Rox Use of Weak Hash (CVE-2025-3576)

A vulnerability in the MIT Kerberos implementation allows GSSAPI- protected messages using RC4-HMAC-MD5 to be spoofed due to weaknesses in the MD5 checksum design. If RC4 is preferred over stronger encryption types, an attacker could exploit MD5 collisions to forge message integrity codes. This m...
