Details

A flaw was found in the X.Org X server. This integer underflow vulnerability, specifically in the XKB compatibility map handling, allows an attacker with local or remote X11 server access to trigger a buffer read overrun. This can lead to memory-safety violations and potentially a denial of service (DoS) or other severe impacts.

Details

A flaw was found in open-iscsi's iscsiuio component. This vulnerability involves an integer underflow and out-of-bounds read during Dynamic Host Configuration Protocol for IPv6 (DHCPv6) packet parsing. Specifically, crafted DHCPv6 Advertise traffic with a short User Datagram Protocol (UDP) length can cause the DHCPv6 payload length to underflow. An unauthenticated attacker on an adjacent network segment can exploit this by sending specially crafted IPv6 UDP traffic while the client is in an active DHCPv6 exchange, leading to a denial of service due to a process crash or service disruption.

GHSA-G77G-V33M-X9RH

Vulnerability from github – Published: 2026-05-08 15:31 – Updated: 2026-05-15 15:30
VLAI
Details

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

media: chips-media: wave5: Fix PM runtime usage count underflow

Replace pm_runtime_put_sync() with pm_runtime_dont_use_autosuspend() in the remove path to properly pair with pm_runtime_use_autosuspend() from probe. This allows pm_runtime_disable() to handle reference count cleanup correctly regardless of current suspend state.

The driver calls pm_runtime_put_sync() unconditionally in remove, but the device may already be suspended due to autosuspend configured in probe. When autosuspend has already suspended the device, the usage count is 0, and pm_runtime_put_sync() decrements it to -1.

This causes the following warning on module unload:

------------[ cut here ]------------ WARNING: CPU: 1 PID: 963 at kernel/kthread.c:1430 kthread_destroy_worker+0x84/0x98 ... vdec 30210000.video-codec: Runtime PM usage count underflow!
