CVE-2026-72083: Software Security Vulnerability Vulnerability
CRITICALCVE-2026-72083 is a CRITICAL (CVSS 9.8) security vulnerability vulnerability (CWE-416: Use After Free) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product reuses or references memory after it has been freed. at some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.. Remediation is available in the latest vendor maintenance releases.

Security Impact
CVSS: 9.8
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
How to Fix CVE-2026-72083
To remediate this vulnerability, upgrade all affected Software dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:treeHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2026-72083, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:treeAnalyze the terminal output to locate any version of Software in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.
Note: The mvn dependency:tree command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-416: Use After Free, where the product reuses or references memory after it has been freed. at some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer. In Software, software state validation or input boundaries are circumvented during processing.

"details" : "In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: target: core: Fix iSCSI ISID use-after-free in REGISTER AND MOVE\n\ncore_scsi3_emulate_pro_register_and_move() maps the PERSISTENT RESERVE OUT\nparameter list with transport_kmap_data_sg() and parses the destination\nTransportID with target_parse_pr_out_transport_id(). For an iSCSI\nTransportID (FORMAT CODE 01b), iscsi_parse_pr_out_transport_id() returns\nthe ISID in iport_ptr as a raw pointer into that mapped buffer.\n\nThe function then unmaps the buffer with transport_kunmap_data_sg() before\ndereferencing iport_ptr in strcmp(), __core_scsi3_locate_pr_reg() and\ncore_scsi3_alloc_registration(). When the parameter list spans more than\none page (PARAMETER LIST LENGTH > 4096), transport_kmap_data_sg() uses\nvmap() and transport_kunmap_data_sg() does vunmap(), so the kernel virtual\naddress backing iport_ptr is torn down and every subsequent dereference is\na use-after-free read of the unmapped region.\n\nKeep the parameter list mapped until iport_ptr is no longer needed: drop\nthe early transport_kunmap_data_sg() and unmap once on the success path,\nright before returning. The error paths already unmap through the existing\n\"if (buf) transport_kunmap_data_sg(cmd)\" at the out: label, which now runs\non every post-map error exit because buf is no longer cleared early. Only\nreads of the mapping happen while spinlocks are held; the map and unmap\ncalls remain outside any lock. The sibling caller\ncore_scsi3_decode_spec_i_port() already uses the buffer before unmapping it\nand is left unchanged.",
