CVE-2024-27431 (GCVE-0-2024-27431)

Vulnerability from cvelistv5 – Published: 2024-05-17 12:02 – Updated: 2025-05-04 09:04

Title

cpumap: Zero-initialise xdp_rxq_info struct before running XDP program

Summary

In the Linux kernel, the following vulnerability has been resolved: cpumap: Zero-initialise xdp_rxq_info struct before running XDP program When running an XDP program that is attached to a cpumap entry, we don't initialise the xdp_rxq_info data structure being used in the xdp_buff that backs the XDP program invocation. Tobias noticed that this leads to random values being returned as the xdp_md->rx_queue_index value for XDP programs running in a cpumap. This means we're basically returning the contents of the uninitialised memory, which is bad. Fix this by zero-initialising the rxq data structure before running the XDP program.

Severity ?

5.5 (Medium)

Tobias noticed that this leads to\nrandom values being returned as the xdp_md-\u003erx_queue_index value for XDP\nprograms running in a cpumap.\n\nThis means we\u0027re basically returning the contents of the uninitialised\nmemory, which is bad. Fix this by zero-initialising the rxq data\nstructure before running the XDP program."
