In the Linux kernel, the following vulnerabilities have been resolved: rxrpc: A race condition in rxrpcexitnet has been fixed. The current code may lead to the following race conditions: CPU0 vs. CPU1 c rxrpcexitnet rxrpcpeerkeepaliveworker if rxnet-live rxnet-live = false;...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fixed an oops due to the absence of a prealloc backlog struct. If an AFRXRPC service socket is opened and bound, but the calls are pre-allocated, then rxrpcallocincomingcall will cause an oops because the rxrpcbacklog stru...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: - rxrpc: Fixed the locking mechanism in rxrpc’s sendmsg function. - Three bugs were fixed in the implementation of rxrpc’s sendmsg function: 1 The rxrpcnewclientcall function should release the socket lock when returning an...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fixed the rxrpclocal leak in rxrpclookuppeer. It is necessary to call rxrpcPutlocal for the peer candidate before kfree, as it holds a reference to rxrpclocal. DH: v2: The peer freeing code has been abstracted into a...

Astra Linux – Vulnerability in Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: rxrpc: The issue of delayed ACKs was fixed, so that the reference serial number is no longer set. The construction of delayed ACKs was corrected to ensure that the reference serial number is not set, as it cannot be used as a...

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-2026-74431

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-2026-74427

A flaw was found in the AFS Andrew File System component of the Linux kernel. During the teardown of an AFS network namespace, a work item responsible for managing preallocated resources rxrpc call/connection/peer queue may not be properly canceled. This improper resource handling could lead to a...

CVE-2026-72374

A flaw was found in the Linux kernel's AFS filesystem client. The AFS client uses an rxrpc server for callback notifications. Its message parsers incorrectly convert the -EAGAIN return value to 0 when the last packet has not been fully received but all currently queued data is consumed. This...
