| Doc Text: |
A flaw was discovered in the Linux kernel's IPv6 implementation, specifically within the inet6_rtm_getaddr() function. The issue arises when user space provides a valid IFA_TARGET_NETNSID value but omits the IFA_ADDRESS and IFA_LOCAL attributes. In such cases, the function returns an -EINVAL error while inadvertently increasing the reference count of the struct net object, leading to a potential memory leak. This flaw has been addressed by ensuring that the reference count is properly managed, preventing unintended resource retention. Users are advised to update their Linux kernel to a version that includes this fix to maintain system stability and prevent resource leaks.

Created kernel tracking bugs for this issue: Affects: fedora-all [bug 2281098] The result of automatic check (that is developed by Alexander Larkin) for this CVE-2024-27417 is: CHECK Maybe valid. Check manually. with impact MODERATE (that is approximation based on flags REMOTE SIMPLEFIX LEAK NETWORK ; these flags parsed automatically based on patche data). Such automatic check happens only for Low/Moderates (and only when not from reporter, but parsing already existing CVE). Highs always checked manually (I check it myself and then we check it again in Remediation team). In rare cases some of the Moderates could be increased to High later. This issue has been addressed in the following products: Red Hat Enterprise Linux 9.2 Extended Update Support Via RHSA-2024:4823 https://access.redhat.com/errata/RHSA-2024:4823 This issue has been addressed in the following products: Red Hat Enterprise Linux 9.2 Extended Update Support Via RHSA-2024:4831 https://access.redhat.com/errata/RHSA-2024:4831 This issue has been addressed in the following products: Red Hat Enterprise Linux 9 Via RHSA-2024:5363 https://access.redhat.com/errata/RHSA-2024:5363 |
