CVE-2024-47739

CVE-2024-47739 is a medium-severity vulnerability in the Linux kernel's padata component, affecting its serialization process. The flaw arises when more than 2^32 padata objects are submitted, causing an integer overflow in the sequence number (seq_nr) that leads to incorrect sorting and a subsequent deadlock. This issue has been addressed by implementing unsigned integer wrap-around for proper sorting. The vulnerability has a CVSS score of 5.5 (Medium), indicating a local attack vector with low attack complexity, requiring low privileges, and resulting in high availability impact. There is no impact on confidentiality or integrity. Currently, there is no evidence of active exploitation, nor are there any public exploit modules available in Metasploit, Nuclei, or ExploitDB. Community discussion and media coverage for this CVE are minimal, consistent with a large percentage of reported vulnerabilities.
