  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\ncpumap: Zero-initialise xdp_rxq_info struct before running XDP program\nWhen running an XDP program that is attached to a cpumap entry, we don't\ninitialise the xdp_rxq_info data structure being used in the xdp_buff\nthat backs the XDP program invocation. Tobias noticed that this leads to\nrandom values being returned as the xdp_md->rx_queue_index value for XDP\nprograms running in a cpumap.\nThis means we're 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.", "In the Linux kernel, the following vulnerability has been resolved:\ncpumap: Zero-initialise xdp_rxq_info struct before running XDP program\nThe Linux kernel CVE team has assigned CVE-2024-27431 to this issue.\nUpstream advisory:\nhttps://lore.kernel.org/linux-cve-announce/2024051723-CVE-2024-27431-30ae@gregkh/T" ],
