- Summary
- CVE-2024-53094 affecting package kernel for versions less than 6.6.64.2-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
RDMA/siw: Add sendpage_ok() check to disable MSG_SPLICE_PAGES
While running ISER over SIW, the initiator machine encounters a warning from skb_splice_from_iter() indicating that a slab page is being used in send_page. To address this, it is better to add a sendpage_ok() check within the driver itself, and if it returns 0, then MSG_SPLICE_PAGES flag should be disabled before entering the network stack.
A similar issue has been discussed for NVMe in this thread: https://lore.kernel.org/all/20240530142417.146696-1-ofir.gal@volumez.com/
