CVE-2026-59901 Netty Bzip2Decoder: Infinite Loop in RLE State Machine Leads to Event-Loop Thread Hang

Netty is an asynchronous, event-driven network application framework. Prior to versions 4.1.136.Final and 4.2.16.Final, the Bzip2Decoder handler in Netty's compression codec pipeline is vulnerable to a denial-of-service attack through a malformed bzip2 stream that permanently captures the...

Denial Of Service (DoS)

Netty is vulnerable to Denial of Service DoS. The vulnerability is due to an infinite loop in the run-length encoding RLE state machine within the Bzip2Decoder handler when processing a malformed bzip2 stream, which allows an attacker to exploit the issue by sending a specially crafted bzip2 stre...

GHSA-558V-64GR-WGG4 Netty: [Bzip2Decoder] Infinite Loop in RLE State Machine Leads to Event-Loop Thread Hang

The Bzip2Decoder handler in Netty's compression codec pipeline is vulnerable to a denial-of-service attack through a malformed bzip2 stream that permanently captures the event-loop thread in an infinite loop. The vulnerability exists in the run-length encoding RLE state machine within...

SUSE CVE-2026-63913

In the Linux kernel, the following vulnerability has been resolved: netfilter: conntrack: tcp: do not force CLOSE on invalid-seq RST without direction check An unintended behavior in the TCP conntrack state machine allows a connection to be forced into the CLOSE state using an RST packet with an...

CVE-2026-64205

A flaw was found in the Linux kernel's i2c-i801 driver. This vulnerability allows a local attacker to trigger a hardware state machine corruption during error handling. This can lead to a denial of service DoS, where the system becomes unresponsive due to a continuous stream of error messages and...

CVE-2026-64205

In the Linux kernel, the following vulnerability has been resolved: i2c: i801: fix hardware state machine corruption in error path A severe livelock and subsequent Hung Task panic were observed in the i2c-i801 driver during concurrent Fuzzing. The crash is caused by an unconditional hardware...

In the Linux kernel, the following vulnerability has been resolved: i2c: i801: fix hardware state machine corruption in error path A severe livelock and subsequent Hung Task panic were observed in the i2c-i801 driver during concurrent Fuzzing. The crash is caused by an unconditional hardware...

CVE-2026-64205

CVE-2026-64205 concerns the Linux kernel i2c-i801 driver. The issue stems from an unconditional hardware register cleanup in the error path of i801_access() when i801_check_pre() fails (e.g., -EBUSY). This can bypass ownership of the SMBus controller, yet code proceeds to clear INUSE_STS and rese...
