CVE-2026-76957
libexpat before 2.8.4 lacks handler call depth tracking with custom encoding callbacks. Thus, a use-after-free can occur. NOTE: this is similar to CVE-2026-50219, CVE-2026-56131 and CVE-2026-56412...
CVE-2026-76956
In libexpat 2.8.2 and 2.8.3 before 2.8.4, misinterpretation of getentropy's return code leads to insufficient entropy, which results in being vulnerable to hash flooding attacks, causing a denial of service via crafted XML content...

CVE-2026-76957
CVE-2026-76957 affects libexpat before 2.8.4 . The root cause is the absence of handler call depth tracking when custom encoding callbacks are in use, which can lead to a use-after-free condition. The CVSS 3.1 score is 4.9 (Medium) with a local attack vector, high complexity, and low impact on co...

CVE-2026-76956
In libexpat versions 2.8.2 and 2.8.3 (fixed in 2.8.4), misinterpretation of the getentropy() return code results in insufficient entropy, weakening the hash randomization that protects against hash-flooding. An attacker can send crafted XML content to force excessive hash collisions, causing CPU ...

expat: libexpat: Denial of Service due to incorrect Unicode surrogate handling
A flaw in libexpat's toUtf16 functions mishandles Unicode low surrogates by treating them as high surrogates. An attacker can exploit the resulting out-of-bounds read to trigger an infinite loop, causing a denial of service DoS...
