CVE-2026-31630 rxrpc: proc: size address buffers for %pISpc output

In the Linux kernel, the following vulnerability has been resolved: rxrpc: proc: size address buffers for %pISpc output The AFRXRPC procfs helpers format local and remote socket addresses into fixed 50-byte stack buffers with "%pISpc". That is too small for the longest current-tree IPv6-with-port...

CVE-2026-31630

The CVE-2026-31630 issue affects the Linux kernel RXRPC procfs address formatting: AF_RXRPC procfs helpers used fixed 50-byte buffers to render local/remote socket addresses with "%pISpc", which is insufficient for the longest current IPv6-with-port forms (notably ISATAP paths). The root cause is...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the rxrpcallocclientcall function acquiring key references without releasing them when the call i...

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix use of wrong skb when comparing queued RESP challenge serial In rxrpc post response, the code should be comparing the challenge serial number from the cached response before deciding to switch to a newer response, but...

PT-2026-34985

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An integer overflow exists in the rxgk verify response function. This occurs because token len is rounded up before being checked, which allows the length check to be bypassed...

PT-2026-34994

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the rxrpc component where call removal from the rxnet-calls list used list del init instead of list del rcu. This could lead to an infinite loop when reading...
