CVE-2025-22057

Summary: CVE-2025-22057 affects the Linux kernel networking path for cached destination entries. The upstream fix to move the dst counter decrement from dst_destroy to dst_release was incomplete when CONFIG_DST_CACHE is enabled and OvS+tunnels are used, causing a potential access of freed data. T...

CVE-2024-50036

CVE-2024-50036 is a Linux kernel vulnerability where dst_entries_add() uses per-CPU data that can be freed during netns dismantle, making dst_entries_destroy() race with dst_release() and potentially causing a use-after-free. The issue arises because the count of dsts must be decremented earlier,...

CVE-2024-26834

In the Linux kernel, the following vulnerability has been resolved: netfilter: nftflowoffload: release dst in case direct xmit path is used Direct xmit does not use it since it calls devqueuexmit to send packets, hence it calls dstrelease. kmemleak reports: unreferenced object 0xffff88814f440900...

CVE-2024-26834

The CVE refers to the Linux kernel netfilter nft_flow_offload path: when using the direct xmit path, dst_release is not invoked, leading to a kmemleak-reported unreferenced object. The vulnerability is described as resolved in the Linux kernel, with fixes implemented in the nft_flow_offload flow ...
