Description Preview

The vulnerability in the Linux kernel identified as CVE-2024-47710 is specifically related to the sock_map module. When a map with a large number of buckets is destroyed, the CPU may not yield when necessary, leading to a soft lockup issue. This vulnerability has been addressed by adding a cond_resched() function in sock_hash_free() to ensure proper CPU handling during the destruction of maps with a large number of buckets.

Overview

This vulnerability affects the Linux kernel versions 5bed77b0a2a0e6b6bc0ae8e851cafb38ef0374df to bc05f6855642cff3c0eeb63060b35d8c4f8a851d, as well as versions 75e68e5bf2c7fa9d3e874099139df03d5952a3e1 to b1339be951ad31947ae19bc25cb08769bf255100. It results in a soft lockup issue when destroying maps with a large number of buckets.

Remediation

To remediate this vulnerability, users are advised to update their Linux kernel to versions that are not affected by the issue. Specifically, versions 5.8 and above are unaffected, while versions 5.4.285, 5.10.227, 5.15.168, 6.1.113, 6.6.54, 6.10.13, 6.11.2, and 6.12 are also not impacted. Users should ensure they are running a kernel version that falls within the unaffected range to mitigate the risk of exploitation.
