Linux RxRPC Session Sockets DoS

The vulnerability of the rxrpcpostresponse function in the net/rxrpc/connevent.c module, which is part of the RxRPC session support in Linux kernel, is related to incorrect comparisons when using erroneous factors. Exploiting this vulnerability can allow an attacker to cause service failures...

Linux RxRPC Kernel Heap Buffer Overflow DoS

The vulnerability of the rxrpcpreparsexdryfsrxgk function in the net/rxrpc/key.c module, which is part of the RxRPC session support in the Linux operating system’s kernel, involves integer overflow. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity...

Linux RxRPC Kernel Session Failure

The vulnerability of the rxrpcprocessevent function in the net/rxrpc/connevent.c module, which is part of the RxRPC session support for Linux kernel, relates to incorrect initialization of resources. Exploiting this vulnerability can allow an attacker to cause service failures...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: rxrpc: A double-unlock issue in rxrpcrecvmsg has been fixed. This issue was addressed by correcting the double-unlock operation when handling OOB messages...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: rxrpc: Fixed the handling of a reply packet before data transmission. rxrpcreceivingreply was fixed to handle the reception of a reply packet before rxrpc has a chance to send any request DATA packets during a client call. Thi...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: rxrpc: Fixed the handling of ACKALL packets. The rxrpcinputackall function accepts ACKALL packets without checking whether the call is in a state where outstanding transmit buffers exist. Therefore, a forged ACKALL packet can...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fixed a use-after-free UAF in rxgkissuechallenge. Fixed rxgkissuechallenge to free the page containing the challenge content after invoking the tracepoint, as the whdr passed to the tracepoint points to the just-freed page...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: rxrpc: Fixed a potential infinite loop in rxrpcrecvmsg. Also, fixed the wait in rxrpcrecvmsg by checking the OOB queue...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Do not move a peeked OOB message onto the pending queue. The rxrpcrecvmsgoob function takes an received OOB message from recvmsgoobq. If a response is needed, it moves the message onto the pendingoobq tree. However, only t...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fixed a leak of a released call in recvmsgMSGPEEK. Also, rxrpcrecvmsg was fixed to also release the reference it holds on a already-released call if MSGPEEK is specified the function holds a reference to the call regardles...

CVE-2026-74436

A flaw was found in the Linux kernel. A synchronization issue in the rxrpc component, specifically between rxrpckernelchargeaccept and rxrpcdiscardprealloc, can lead to a use-after-free vulnerability. A local attacker could potentially exploit this flaw, causing a kernel preallocation worker to...

CVE-2026-74435

A flaw was found in the rxrpc subsystem of the Linux kernel. This vulnerability occurs when the rxrpcverifydata function fails to allocate a necessary buffer if the incoming data length is zero. An attacker could exploit this by sending specially crafted network packets, leading to a NULL pointer...

CVE-2026-74434

A flaw was found in the Linux kernel's rxrpc subsystem. When an out-of-band OOB message is read using the MSGPEEK flag in the rxrpcrecvmsgoob function, the message is incorrectly left on one queue while also being added to another. This can lead to the message being freed twice when the socket is...

CVE-2026-74432

A flaw was found in the rxrpc component of the Linux kernel. When the recvmsg function is called with the MSGPEEK flag, it fails to properly release a reference to an already-released call. This oversight can lead to a memory leak, potentially allowing a local attacker to cause a Denial of Servic...

CVE-2026-74431

A flaw was found in the Linux kernel's rxrpc network protocol implementation. This vulnerability could allow an attacker to trigger an infinite loop within the rxrpcrecvmsg function by manipulating out-of-band OOB queue handling. This could lead to a Denial of Service DoS condition, making the...

CVE-2026-74430

A flaw was found in the Linux kernel's rxrpc component. A remote attacker could send a specially crafted ACKALL packet that bypasses state validation. This improper handling of forged packets can lead to a null-pointer dereference, causing a Denial of Service DoS by crashing the system...

CVE-2026-74429

A flaw was found in the Linux kernel's rxrpc component. This vulnerability occurs when the system receives a reply data packet before any request data packets have been sent on a client call. An attacker could potentially exploit this by sending a specially crafted reply packet, leading to a kern...

CVE-2026-74428

A flaw was found in the Linux kernel's rxrpc subsystem. A double unlock vulnerability in the rxrpcrecvmsg function, when processing out-of-band OOB messages, could allow a remote attacker to cause a system crash. This issue leads to a Denial of Service DoS condition...
