CVE-2024-26618 is a memory leak vulnerability in the Linux kernel's arm64/sme subsystem. This flaw occurs when sme_alloc() improperly handles existing storage during reallocation, leading to leaked memory and potential system instability. Specifically, the code reallocates memory without freeing the old allocation, which wastes resources. While the CVSS score is 5.5, indicating a medium severity, the SOCRadar Vulnerability Risk Score (SVRS) of 30 suggests a relatively low level of immediate risk based on current threat intelligence. Although not critical, administrators should apply the fix to prevent resource exhaustion over time. This vulnerability is important to address because unmanaged memory allocation can lead to performance degradation and eventually system failure. Addressing this issue enhances kernel stability and resource management.
