CVE-2024-38544: Linux kernel RDMA may crash during high traffic
CVE-2024-38544 · published 2 years ago
Summary
The Linux kernel packages provided by Canonical (including the HWE and cloud variants) can crash when processing certain network packets if many requests arrive at once. The problem occurs because the system may try to use a packet that has already been freed, leading to a segmentation fault. Updating to the latest kernel version from Canonical resolves the issue by correcting the order in which the packet is handled.

Original advisory text
RDMA/rxe: Fix seg fault in rxe_comp_queue_pkt
In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Fix seg fault in rxe_comp_queue_pkt In rxe_comp_queue_pkt() an incoming response packet skb is enqueued to the resp_pkts queue and then a decision is made whether to run the completer task inline or schedule it. Finally the skb is dereferenced to bump a 'hw' performance counter. This is wrong because if the completer task is already running in a separate thread it may have already processed the skb and freed it which can cause a seg fault. This has been observed infrequently in testing at high scale. This patch fixes this by changing the order of enqueuing the packet until after the counter is accessed.
