CVE-2024-35982 (GCVE-0-2024-35982)

Vulnerability from cvelistv5 – Published: 2024-05-20 09:42 – Updated: 2026-05-12 11:53

Title

batman-adv: Avoid infinite loop trying to resize local TT

Summary

In the Linux kernel, the following vulnerability has been resolved: batman-adv: Avoid infinite loop trying to resize local TT If the MTU of one of an attached interface becomes too small to transmit the local translation table then it must be resized to fit inside all fragments (when enabled) or a single packet. But if the MTU becomes too low to transmit even the header + the VLAN specific part then the resizing of the local TT will never succeed. This can for example happen when the usable space is 110 bytes and 11 VLANs are on top of batman-adv. In this case, at least 116 byte would be needed. There will just be an endless spam of batman_adv: batadv0: Forced to purge local tt entries to fit new maximum fragment MTU (110) in the log but the function will never finish. Problem here is that the timeout will be halved all the time and will then stagnate at 0 and therefore never be able to reduce the table even more. There are other scenarios possible with a similar result. The number of BATADV_TT_CLIENT_NOPURGE entries in the local TT can for example be too high to fit inside a packet. Such a scenario can therefore happen also with only a single VLAN + 7 non-purgable addresses - requiring at least 120 bytes. While this should be handled proactively when: * interface with too low MTU is added * VLAN is added * non-purgeable local mac is added * MTU of an attached interface is reduced * fragmentation setting gets disabled (which most likely requires dropping attached interfaces) not all of these scenarios can be prevented because batman-adv is only consuming events without the the possibility to prevent these actions (non-purgable MAC address added, MTU of an attached interface is reduced). It is therefore necessary to also make sure that the code is able to handle also the situations when there were already incompatible system configuration are present.

This\ncan for example happen when the usable space is 110 bytes and 11 VLANs are\non top of batman-adv. In this case, at least 116 byte would be needed.\nThere will just be an endless spam of\n\n   batman_adv: batadv0: Forced to purge local tt entries to fit new maximum fragment MTU (110)\n\nin the log but the function will never finish. Problem here is that the\ntimeout will be halved all the time and will then stagnate at 0 and\ntherefore never be able to reduce the table even more.\n\nThere are other scenarios possible with a similar result. The number of\nBATADV_TT_CLIENT_NOPURGE entries in the local TT can for example be too\nhigh to fit inside a packet. Such a scenario can therefore happen also with\nonly a single VLAN + 7 non-purgable addresses - requiring at least 120\nbytes.\n\nWhile this should be handled proactively when:\n\n* interface with too low MTU is added\n* VLAN is added\n* non-purgeable local mac is added\n* MTU of an attached interface is reduced\n* fragmentation setting gets disabled (which most likely requires dropping\n  attached interfaces)\n\nnot all of these scenarios can be prevented because batman-adv is only\nconsuming events without the the possibility to prevent these actions\n(non-purgable MAC address added, MTU of an attached interface is reduced).\nIt is therefore necessary to also make sure that the code is able to handle\nalso the situations when there were already incompatible system\nconfiguration are present."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
