Vulnerability from github – Published: 2022-05-24 17:29 – Updated: 2022-10-07 18:15
VLAI
Details

An integer underflow in dpdk versions before 18.11.10 and before 19.11.5 in the move_desc function can lead to large amounts of CPU cycles being eaten up in a long running loop. An attacker could cause move_desc to get stuck in a 4,294,967,295-count iteration loop. Depending on how vhost_crypto is being used this could prevent other VMs or network tasks from being serviced by the busy DPDK lcore for an extended period.

GHSA-PWH4-8CRG-2XVF

Vulnerability from github – Published: 2026-06-25 09:31 – Updated: 2026-07-06 18:30
VLAI
Details

In the Linux kernel, the following vulnerability has been resolved:

thunderbolt: Reject zero-length property entries in validator

tb_property_entry_valid() accepts entries with length == 0 for DIRECTORY, DATA, and TEXT types. A zero-length TEXT entry passes validation but causes an underflow in the null-termination logic:

property->value.text[property->length * 4 - 1] = '\0';

When property->length is 0 this writes to offset -1 relative to the allocation.

Reject zero-length entries early in the validator since they have no valid representation in the XDomain property protocol.

5.5 (Medium)

GHSA-PWX7-84P4-42QC

Vulnerability from github – Published: 2026-02-04 18:30 – Updated: 2026-03-13 21:31
VLAI
Details

In the Linux kernel, the following vulnerability has been resolved:

vsock/virtio: fix potential underflow in virtio_transport_get_credit()

The credit calculation in virtio_transport_get_credit() uses unsigned arithmetic:

ret = vvs->peer_buf_alloc - (vvs->tx_cnt - vvs->peer_fwd_cnt);

If the peer shrinks its advertised buffer (peer_buf_alloc) while bytes are in flight, the subtraction can underflow and produce a large positive value, potentially allowing more data to be queued than the peer can handle.

Reuse virtio_transport_has_space() which already handles this case and add a comment to make it clear why we are doing that.

[Stefano: use virtio_transport_has_space() instead of duplicating the code] [Stefano: tweak the commit message]

An integer underflow vulnerability exists in the sopen_FAMOS_read functionality of The Biosig Project libbiosig 2.5.0 and Master Branch (ab0ee111). A specially crafted .famos file can lead to an out-of-bounds write which in turn can lead to arbitrary code execution. An attacker can provide a malicious file to trigger this vulnerability.

Details

In the Linux kernel, the following vulnerability has been resolved:

cifs: fix underflow in parse_server_interfaces()

In this loop, we step through the buffer and after each item we check if the size_left is greater than the minimum size we need. However, the problem is that "bytes_left" is type ssize_t while sizeof() is type size_t. That means that because of type promotion, the comparison is done as an unsigned and if we have negative bytes left the loop continues instead of ending.

Severity
6.7 (Medium)
