CVE-2026-90678

An issue was discovered in HAProxy 3.3.0 through 3.4.4 and in 3.5-dev1 through 3.5-dev5. Exploitation requires an HTTP/3 frontend: HAProxy must be built with QUIC support and configured with a QUIC bind listener, and the affected traffic must reach a backend over HTTP/1.1 using chunked transfer...

CVE-2026-90678

HAProxy 3.3.0 through 3.4.4 and 3.5-dev1 through 3.5-dev5 are affected by an HTTP request smuggling vulnerability in the HTTP/3 (QUIC) multiplexer . When an HTTP/3 request with no Content-Length header is forwarded to an HTTP/1.1 backend using chunked transfer coding on a reused connection, the d...

Name of the Vulnerable Software and Affected Versions HAProxy versions 3.3.0 through 3.4.4 HAProxy versions 3.5-dev1 through 3.5-dev5 Description An issue exists in HAProxy when using an HTTP/3 frontend built with QUIC support and a QUIC bind listener, where traffic is routed to a backend over...

curl: HTTP/1.1 response framing violation and unsafe connection reuse when transfer decoding is disabled

Summary: libcurl can incorrectly reuse an HTTP/1.1 connection after a response containing both Content-Length and a non-chunked Transfer-Encoding when transfer decoding is disabled with CURLOPTHTTPTRANSFERDECODING = 0L --raw behavior. In this state, libcurl can treat Content-Length as the respons...

Linux Distros Unpatched Vulnerability : CVE-2026-89531

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - svcrdma: Reject connection when transport allocation fails handleconnectreq returns without action when svcrdmacreatexprt fails to allocate the new transport.

Linux Distros Unpatched Vulnerability : CVE-2026-80990

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - net: thunderbolt: Release the Rx HopID that was handed out on mismatch tbxdomainallocinhopid passes the wanted HopID to idaallocrange as the lower bound, so a...

CVE-2026-89549

A flaw was found in the sunrpc component of the Linux kernel. When the nfsd service runs with fewer threads than available pools, a transport can be routed to a pool with no active threads. This prevents the connection from being processed, causing it to hang indefinitely. This can lead to a Deni...

CVE-2026-89488

A flaw was found in the Linux kernel's Open vSwitch OVS component. An unprivileged user, operating from a user and network namespace, can trigger a use-after-free vulnerability during network namespace teardown. This occurs because packet processing attempts to use connection tracking CT limit...

CVE-2026-80990

A flaw was found in the Linux kernel's Thunderbolt networking driver. An issue in the tbnetconnectedwork function can lead to a resource leak. When an unexpected HopID is allocated during an XDomain connection, the ID is not properly released, causing it to remain active without a reference. This...

CVE-2026-80979

A flaw was found in the Linux kernel's Shared Memory Communications SMC component. During connection termination, the SMC component may fail to properly unregister a connection before draining its receive tasklet. This can lead to a use-after-free vulnerability, where a freed memory buffer is...

CVE-2026-80980

A flaw was found in the Linux kernel's SMC Server Message Block over Remote Direct Memory Access protocol implementation. A concurrency issue exists where three connection state flags killed, freed, and outofsync share a single byte in the smcconnection structure without proper locking mechanisms...

CVE-2026-80990

In the Linux kernel, the following vulnerability has been resolved: net: thunderbolt: Release the Rx HopID that was handed out on mismatch tbxdomainallocinhopid passes the wanted HopID to idaallocrange as the lower bound, so a taken id is not an error there: the allocator returns the next free on...

CVE-2026-80979

In the Linux kernel, the following vulnerability has been resolved: net/smc: unregister the connection before draining the rx tasklet smcconnfree calls smcismunsetconn only while the link group is still on its device list, and never sets conn-killed. smclgrterminatesched unlinks the group...

AZL-100361 CVE-2026-80980 affecting package kernel 6.6.157.1-1

In the Linux kernel, the following vulnerability has been resolved: net/smc: stop killed, freed and outofsync sharing a byte The three connection state flags are single-bit bitfields, so they occupy one byte of struct smcconnection and every store to one is a read-modify-write of the other two: u...

AZL-100082 CVE-2026-80979 affecting package kernel for versions less than 6.6.157.1-1
