CVE-2024-42302: Software Security Vulnerability Vulnerability
HIGHCVE-2024-42302 is a HIGH (CVSS 7.8) 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 any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer..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: 7.8
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).
How to Fix CVE-2024-42302
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-2024-42302, 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 any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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\nPCI/DPC: Fix use-after-free on concurrent DPC and hot-removal\n\nKeith reports a use-after-free when a DPC event occurs concurrently to\nhot-removal of the same portion of the hierarchy:\n\nThe dpc_handler() awaits readiness of the secondary bus below the\nDownstream Port where the DPC event occurred. To do so, it polls the\nconfig space of the first child device on the secondary bus. If that\nchild device is concurrently removed, accesses to its struct pci_dev\ncause the kernel to oops.\n\nThat's because pci_bridge_wait_for_secondary_bus() neglects to hold a\nreference on the child device. Before v6.3, the function was only\ncalled on resume from system sleep or on runtime resume. Holding a\nreference wasn't necessary back then because the pciehp IRQ thread\ncould never run concurrently. (On resume from system sleep, IRQs are\nnot enabled until after the resume_noirq phase. And runtime resume is\nalways awaited before a PCI device is removed.)\n\nHowever starting with v6.3, pci_bridge_wait_for_secondary_bus() is also\ncalled on a DPC event. Commit 53b54ad074de (\"PCI/DPC: Await readiness\nof secondary bus after reset\"), which introduced that, failed to\nappreciate that pci_bridge_wait_for_secondary_bus() now needs to hold a\nreference on the child device because dpc_handler() and pciehp may\nindeed run concurrently. The commit was backported to v5.10+ stable\nkernels, so that's the oldest one affected.\n\nAdd the missing reference acquisition.\n\nAbridged stack trace:\n\n BUG: unable to handle page fault for address: 00000000091400c0\n CPU: 15 PID: 2464 Comm: irq/53-pcie-dpc 6.9.0\n RIP: pci_bus_read_config_dword+0x17/0x50\n pci_dev_wait()\n pci_bridge_wait_for_secondary_bus()\n dpc_reset_link()\n pcie_do_recovery()\n dpc_handler()",
