CVE-2018-12928
LowSummary
W jądrze Linux w wersji 4.15.0 odkryto dereferencję wskaźnika NULL w funkcji hfs_ext_read_extent w module hfs. Może to wystąpić podczas montowania spreparowanego systemu plików hfs.
Risk Assessment
Wykorzystanie tej podatności może prowadzić do awarii systemu lub nieprzewidzianego zachowania, co zagraża stabilności i bezpieczeństwu systemu operacyjnego.
Recommendation
Zaleca się aktualizację jądra Linux do najnowszej wersji, aby usunąć tę podatność oraz monitorowanie systemów w celu wykrycia potencjalnych prób jej wykorzystania.

Hazelcast prior to 5.4.5, 5.5.10, and 5.6.1 contains improper validation of data supplied by a malicious client able to connect to a cluster, allowing arbitrary reads from a cluster member's Java heap, off-heap data, and JVM process address space. The same flaw can crash cluster members and, in some Hazelcast Enterprise Edition configurations, corrupt memory with possible arbitrary code execution. This issue is fixed in versions 5.4.5, 5.5.10, 5.6.1, and 5.7.0.
- CVE-2026-107722Critical
fast-jwt from 6.2.0 until 6.3.0 can misclassify RSA public-key text as an HMAC secret when the key has non-whitespace content before its PEM header. In src/crypto.js, performDetectPublicKeyAlgorithms trims whitespace but publicKeyPemMatcher remains start-anchored, so comments, control characters, zero-width characters, or wrapper text can prevent PEM detection and reach the HMAC fallback. An attacker who knows the public key bytes can sign arbitrary HS256 claims with that public material when HS256 is inferred or allowed, resulting in authentication or authorization bypass. An asymmetric-only algorithm allowlist prevents the attack. This issue is fixed in version 6.3.0.
Original NVD description (English source)
In the Linux kernel 4.15.0, a NULL pointer dereference was discovered in hfs_ext_read_extent in hfs.ko. This can occur during a mount of a crafted hfs filesystem.
