CVE-2025-37799 (GCVE-0-2025-37799)

Title

vmxnet3: Fix malformed packet sizing in vmxnet3_process_xdp

Summary

In the Linux kernel, the following vulnerability has been resolved: vmxnet3: Fix malformed packet sizing in vmxnet3_process_xdp vmxnet3 driver's XDP handling is buggy for packet sizes using ring0 (that is, packet sizes between 128 - 3k bytes). We noticed MTU-related connectivity issues with Cilium's service load- balancing in case of vmxnet3 as NIC underneath. A simple curl to a HTTP backend service where the XDP LB was doing IPIP encap led to overly large packet sizes but only for *some* of the packets (e.g. HTTP GET request) while others (e.g. the prior TCP 3WHS) looked completely fine on the wire. In fact, the pcap recording on the backend node actually revealed that the node with the XDP LB was leaking uninitialized kernel data onto the wire for the affected packets, for example, while the packets should have been 152 bytes their actual size was 1482 bytes, so the remainder after 152 bytes was padded with whatever other data was in that page at the time (e.g. we saw user/payload data from prior processed packets). We only noticed this through an MTU issue, e.g. when the XDP LB node and the backend node both had the same MTU (e.g. 1500) then the curl request got dropped on the backend node's NIC given the packet was too large even though the IPIP-encapped packet normally would never even come close to the MTU limit. Lowering the MTU on the XDP LB (e.g. 1480) allowed to let the curl request succeed (which also indicates that the kernel ignored the padding, and thus the issue wasn't very user-visible). Commit e127ce7699c1 ("vmxnet3: Fix missing reserved tailroom") was too eager to also switch xdp_prepare_buff() from rcd->len to rbi->len. It really needs to stick to rcd->len which is the actual packet length from the descriptor. The latter we also feed into vmxnet3_process_xdp_small(), by the way, and it indicates the correct length needed to initialize the xdp->{data,data_end} parts. For e127ce7699c1 ("vmxnet3: Fix missing reserved tailroom") the relevant part was adapting xdp_init_buff() to address the warning given the xdp_data_hard_end() depends on xdp->frame_sz. With that fixed, traffic on the wire looks good again.

A simple curl to a HTTP\nbackend service where the XDP LB was doing IPIP encap led to overly large\npacket sizes but only for *some* of the packets (e.g. HTTP GET request)\nwhile others (e.g. the prior TCP 3WHS) looked completely fine on the wire.\n\nIn fact, the pcap recording on the backend node actually revealed that the\nnode with the XDP LB was leaking uninitialized kernel data onto the wire\nfor the affected packets, for example, while the packets should have been\n152 bytes their actual size was 1482 bytes, so the remainder after 152 bytes\nwas padded with whatever other data was in that page at the time (e.g. we\nsaw user/payload data from prior processed packets).\n\nWe only noticed this through an MTU issue, e.g. when the XDP LB node and\nthe backend node both had the same MTU (e.g. 1500) then the curl request\ngot dropped on the backend node\u0027s NIC given the packet was too large even\nthough the IPIP-encapped packet normally would never even come close to\nthe MTU limit. Lowering the MTU on the XDP LB (e.g. 1480) allowed to let\nthe curl request succeed (which also indicates that the kernel ignored the\npadding, and thus the issue wasn\u0027t very user-visible).\n\nCommit e127ce7699c1 (\"vmxnet3: Fix missing reserved tailroom\") was too eager\nto also switch xdp_prepare_buff() from rcd-\u003elen to rbi-\u003elen. It really needs\nto stick to rcd-\u003elen which is the actual packet length from the descriptor.\nThe latter we also feed into vmxnet3_process_xdp_small(), by the way, and\nit indicates the correct length needed to initialize the xdp-\u003e{data,data_end}\nparts. For e127ce7699c1 (\"vmxnet3: Fix missing reserved tailroom\") the\nrelevant part was adapting xdp_init_buff() to address the warning given the\nxdp_data_hard_end() depends on xdp-\u003eframe_sz. With that fixed, traffic on\nthe wire looks good again."

CVE-2025-21887 (GCVE-0-2025-21887)

Vulnerability from cvelistv5 – Published: 2025-03-27 14:57 – Updated: 2025-12-06 21:38

Title

ovl: fix UAF in ovl_dentry_update_reval by moving dput() in ovl_link_up

Summary

In the Linux kernel, the following vulnerability has been resolved: ovl: fix UAF in ovl_dentry_update_reval by moving dput() in ovl_link_up The issue was caused by dput(upper) being called before ovl_dentry_update_reval(), while upper->d_flags was still accessed in ovl_dentry_remote(). Move dput(upper) after its last use to prevent use-after-free. BUG: KASAN: slab-use-after-free in ovl_dentry_remote fs/overlayfs/util.c:162 [inline] BUG: KASAN: slab-use-after-free in ovl_dentry_update_reval+0xd2/0xf0 fs/overlayfs/util.c:167 Call Trace: <TASK> __dump_stack lib/dump_stack.c:88 [inline] dump_stack_lvl+0x116/0x1f0 lib/dump_stack.c:114 print_address_description mm/kasan/report.c:377 [inline] print_report+0xc3/0x620 mm/kasan/report.c:488 kasan_report+0xd9/0x110 mm/kasan/report.c:601 ovl_dentry_remote fs/overlayfs/util.c:162 [inline] ovl_dentry_update_reval+0xd2/0xf0 fs/overlayfs/util.c:167 ovl_link_up fs/overlayfs/copy_up.c:610 [inline] ovl_copy_up_one+0x2105/0x3490 fs/overlayfs/copy_up.c:1170 ovl_copy_up_flags+0x18d/0x200 fs/overlayfs/copy_up.c:1223 ovl_rename+0x39e/0x18c0 fs/overlayfs/dir.c:1136 vfs_rename+0xf84/0x20a0 fs/namei.c:4893 ... </TASK>

CVE-2025-21759 (GCVE-0-2025-21759)

Vulnerability from cvelistv5 – Published: 2025-02-27 02:18 – Updated: 2025-05-04 07:20

Title

ipv6: mcast: extend RCU protection in igmp6_send()

Summary

In the Linux kernel, the following vulnerability has been resolved: ipv6: mcast: extend RCU protection in igmp6_send() igmp6_send() can be called without RTNL or RCU being held. Extend RCU protection so that we can safely fetch the net pointer and avoid a potential UAF. Note that we no longer can use sock_alloc_send_skb() because ipv6.igmp_sk uses GFP_KERNEL allocations which can sleep. Instead use alloc_skb() and charge the net->ipv6.igmp_sk socket under RCU protection.

Severity ?

7.8 (High)
