CVE-2007-6151
HighSummary
Funkcja isdn_ioctl w pliku isdn_common.c w jądrze Linux 2.6.23 pozwala lokalnym użytkownikom na wywołanie odmowy usługi poprzez spreparowaną strukturę ioctl, w której iocts nie jest zakończony znakiem null, co prowadzi do przepełnienia bufora.
Risk Assessment
Atakujący może wykorzystać tę podatność do zakłócenia działania systemu, co może prowadzić do przestojów w usługach i utraty dostępności.
Recommendation
Zaleca się aktualizację jądra Linux do najnowszej wersji, aby usunąć tę podatność oraz monitorowanie systemu pod kątem nieautoryzowanych działań.

- CVE-2026-53939Critical
In cjose versions 0.6.1 through 0.6.2.5, when encrypting a JWE using AES-CBC-HMAC content-encryption algorithms (A128CBC-HS256, A192CBC-HS384, A256CBC-HS512) with any key-management algorithm that generates a fresh content-encryption key (CEK), the CEK is all zero bytes instead of being randomly generated. The resulting JWE is encrypted and authenticated under a fixed, publicly known key, allowing anyone who obtains the JWE to recover plaintext and forge or modify content. Fixed in 0.6.2.6 by generating CEK from RAND_bytes.
- CVE-2026-53581Critical
OPNsense is a FreeBSD based firewall and routing platform. Prior to version 26.1.9 of opnsense/core and version 26.4_20 of BE/opnsense/core, a path traversal vulnerability in the NTP configuration module allows an attacker to overwrite arbitrary files on the system as the root user. By manipulating the GPS or PPS serial port parameter, an attacker with access to the NTP configuration can escape the intended directory and write user-controlled data to any file.
- CVE-2026-85982Critical
The Auth0 AD/LDAP Connector is vulnerable to stored Cross-Site Scripting (XSS) issues due to improper HTML encoding of data in search results and updater log content displayed in the admin panel. An authenticated user with privileges to modify directory attributes, or a low-privileged local user on the host, could insert script content that executes in an administrator's browser.
Original NVD description (English source)
The isdn_ioctl function in isdn_common.c in Linux kernel 2.6.23 allows local users to cause a denial of service via a crafted ioctl struct in which iocts is not null terminated, which triggers a buffer overflow.
