发布于3月6日3月6日 Members Rocky Linux: CVE-2024-35958: kernel (Multiple Advisories) Severity 4 CVSS (AV:L/AC:M/Au:N/C:P/I:P/A:P) Published 05/20/2024 Created 07/16/2024 Added 07/16/2024 Modified 11/18/2024 Description In the Linux kernel, the following vulnerability has been resolved: net: ena: Fix incorrect descriptor free behavior ENA has two types of TX queues: - queues which only process TX packets arriving from the network stack - queues which only process TX packets forwarded to it by XDP_REDIRECT or XDP_TX instructions The ena_free_tx_bufs() cycles through all descriptors in a TX queue and unmaps + frees every descriptor that hasn't been acknowledged yet by the device (uncompleted TX transactions). The function assumes that the processed TX queue is necessarily from the first category listed above and ends up using napi_consume_skb() for descriptors belonging to an XDP specific queue. This patch solves a bug in which, in case of a VF reset, the descriptors aren't freed correctly, leading to crashes.
