CVSS v3.1 |
| CAI Content Credentials is affected by an Improper Input Validation vulnerability that could result in a Security feature bypass. An attacker could leverage this vulnerability to bypass security measures and gain unauthorized limited write access. Exploitation of this issue does not require user interaction. |
| Improper synchronization in the OpenVPN ovpn-dco-win for Windows versions 0.6.5 through 1.3.5 and 2.4.0 through 2.8.7 allows local attackers to trigger a deadlock via a crafted write to the ovpn-dco device, causing the host to become unresponsive. |
| In the Linux kernel, the following vulnerability has been resolved:
ibmveth: h_free logical LAN on open-fail after register
ibmveth_open() registers the logical LAN, then allocates the RX
buffer pools. A pool failure jumps to out_free_buffer_pools without
h_free_logical_lan(), so PHYP still owns the buffer-list page when
it is unmapped. request_irq() failure already issued the hypercall
before taking the same label.
Move that h_free to the shared post-register unwind so both paths
deregister before the buffer list is unmapped. |
| In the Linux kernel, the following vulnerability has been resolved:
gve: fix XSK buffer leak when rings are stopped
GVE does not free XSK buffers when resetting ring state as a part of
stopping queues. This causes all XSK buffers which are posted to the
NIC to be leaked.
Free XSK buffers attached to an allocated buf_state when stopping rings.
This issue was hit in production. |
| In the Linux kernel, the following vulnerability has been resolved:
gve: fix napi_disable deadlock when attempting to disable XSK pools
When disabling XSK pools, GVE calls the unlocked versions of
napi_disable and napi_enable. However, the netdev lock has already been
acquired before ndo_bpf is called because GVE supports queue management
ops. Calling the unlocked versions of napi_disable/enable results in a
deadlock when attempting to disable XSK pools, as the thread attempts to
re-acquire a lock it already holds.
Update the NAPI calls to use the locked versions.
This issue was found in production. |
| In the Linux kernel, the following vulnerability has been resolved:
tcp: reject net_iov in zerocopy receive mapping hints
After copying a readable prefix, receive_fallback_to_copy() asks
tcp_zerocopy_set_hint_for_skb() where page mapping can resume. If the
next skb is unreadable, find_next_mappable_frag() passes its net_iov
fragment to can_map_frag().
skb_frag_page() returns NULL for a net_iov, but can_map_frag()
dereferences it in PageCompound(). A v7.2 KASAN run on a connected TCP
socket with 64 readable bytes followed by a 4096-byte NET_IOV_DMABUF
fragment reported:
BUG: KASAN: null-ptr-deref in can_map_frag
tcp_zerocopy_receive -> can_map_frag
Kernel panic - not syncing: KASAN: panic_on_warn set
The diagnostic inserted the net_iov directly because the test host has
no devmem-capable NIC. Hardware end-to-end reachability remains untested
and requires CONFIG_NET_DEVMEM plus a supported DMA-buf-bound RX queue.
Reject all net_iov fragments before skb_frag_page(). This covers both
DMABUF and IOURING net_iov types while leaving page-backed checks
unchanged. With the guard, the same queue copied the readable prefix,
returned a 4096-byte skip hint, and completed without a fault. |
