Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 5.3.11
Description
A memory leak in the
alloc sgtable() function in the Linux kernel allows attackers to cause a denial of service (memory consumption) by triggering alloc page() failures. This issue is related to the drivers/net/wireless/intel/iwlwifi/fw/dbg.c file. The vulnerability can be exploited by remote attackers to cause a denial of service.Recommendations
For Linux kernel versions prior to 5.3.11, update to a version that includes the fix for this issue to prevent memory leaks and potential denial of service attacks. As a temporary workaround, consider restricting access to the
alloc sgtable() function to minimize the risk of exploitation.Correção
