CVE-2026-57433: CWE-190 Integer Overflow or Wraparound in HAARG Storable
CVE-2026-57433 is a critical integer overflow vulnerability in the Storable Perl module before version 3.41. It occurs during deserialization of a crafted SX_HOOK record, where a signed 32-bit item count is read and incremented, causing a wraparound to a negative value. This leads to a panic and termination of the deserialization process.
AI Analysis
Technical Summary
The vulnerability in Storable versions prior to 3.41 involves a signed integer overflow when deserializing a crafted SX_HOOK record. Specifically, the function retrieve_hook_common reads a signed 32-bit count from the record and adds one before passing it to av_extend. If the count is at the maximum 32-bit signed integer value (I32_MAX), the addition wraps around to a negative number. This causes av_extend to receive a negative count, triggering a panic and aborting the deserialization. This can lead to denial of service and potentially impact confidentiality and integrity due to the high CVSS score.
Potential Impact
Successful exploitation results in a denial of service by causing the deserialization process to panic and terminate. The CVSS score of 9.8 indicates high impact on confidentiality, integrity, and availability, though the primary observed effect is a crash during deserialization. There is no confirmed exploit in the wild.
Mitigation Recommendations
No official fix or patch is currently confirmed for this vulnerability. Users should upgrade to Storable version 3.41 or later once available. Until then, avoid deserializing untrusted data with affected versions. Monitor the vendor advisory for updates on remediation.
