SUSE CVE-2026-31633

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix integer overflow in rxgkverifyresponse In rxgkverifyresponse, there's a potential integer overflow due to rounding up tokenlen before checking it, thereby allowing the length check to be bypassed. Fix this by checking...

SUSE CVE-2026-31635

In the Linux kernel, the following vulnerability has been resolved: rxrpc: fix oversized RESPONSE authenticator length check rxgkverifyresponse decodes authlen from the packet and is supposed to verify that it fits in the remaining bytes. The existing check is inverted, so oversized RESPONSE...

SUSE CVE-2026-31637

In the Linux kernel, the following vulnerability has been resolved: rxrpc: reject undecryptable rxkad response tickets rxkaddecryptticket decrypts the RXKAD response ticket and then parses the buffer as plaintext without checking whether cryptoskcipherdecrypt succeeded. A malformed RESPONSE can...

SUSE CVE-2026-31638

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Only put the call ref if one was acquired rxrpcinputpacketonconn can process a to-client packet after the current client call on the channel has already been torn down. In that case chan-call is NULL, rxrpctrygetcall retur...

SUSE CVE-2026-31639

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix key reference count leak from call-key When creating a client call in rxrpcallocclientcall, the code obtains a reference to the key. This is never cleaned up and gets leaked when the call is destroyed. Fix this by...

SUSE CVE-2026-31641

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix RxGK token loading to check bounds rxrpcpreparsexdryfsrxgk reads the raw key length and ticket length from the XDR token as u32 values and passes each through roundupx, 4 before using the rounded value for validation a...

SUSE CVE-2026-31642

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix call removal to use RCU safe deletion Fix rxrpc call removal from the rxnet-calls list to use listdelrcu rather than listdelinit to prevent stuffing up reading /proc/net/rxrpc/calls from potentially getting into an...

SUSE CVE-2026-31643

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix key parsing memleak In rxrpcpreparsexdryfsrxgk, the memory attached to token-rxgk can be leaked in a few error paths after it's allocated. Fix this by freeing it in the "rejecttoken:" case...

Linux Distros Unpatched Vulnerability : CVE-2026-31676

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - rxrpc: only handle RESPONSE during service challenge Only process RESPONSE packets while the service connection is still in RXRPCCONNSERVICECHALLENGING. Check...

Linux Distros Unpatched Vulnerability : CVE-2026-31639

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - rxrpc: Fix key reference count leak from call-key When creating a client call in rxrpcallocclientcall, the code obtains a reference to the key. This is never...

CVE-2026-31643

A flaw was found in the Linux kernel's rxrpc subsystem. During key parsing, a memory leak can occur in certain error paths. This vulnerability could allow a local or remote attacker to cause a denial of service by exhausting system memory...

CVE-2026-31642

A flaw was found in the Linux kernel's rxrpc module. This vulnerability occurs due to incorrect handling of call removal, specifically using listdelinit instead of listdelrcu. A local user reading the /proc/net/rxrpc/calls file could potentially trigger an infinite loop, leading to a Denial of...

CVE-2026-31641

A flaw was found in the Linux kernel's rxrpc subsystem. An unprivileged local user could exploit an integer overflow vulnerability in the rxrpcpreparsexdryfsrxgk function. This flaw occurs when processing specially crafted key and ticket lengths, causing an incorrect memory allocation size...

CVE-2026-31640

A flaw was found in the Linux kernel's rxrpc component. This vulnerability occurs in the rxrpcpostresponse function, where the system incorrectly compares a newer network packet's data instead of the expected cached response. This error causes the challenge serial number comparison to always be...

CVE-2026-31637

A flaw was found in the Linux kernel's rxrpc subsystem. A remote attacker could exploit this by sending a malformed RXKAD response ticket. This ticket, with a non-block-aligned length, would cause decryption to fail, yet the system would proceed to process attacker-controlled data. This could lea...

CVE-2026-31635

A flaw was found in the Linux kernel's rxrpc component. An inverted length check in the rxgkverifyresponse function allows oversized RESPONSE authenticators to be accepted. This can lead to an impossible length being passed to skbtosgvec, triggering a BUGON condition and resulting in a system...

CVE-2026-31634

A flaw was found in the Linux kernel's rxrpc subsystem. An issue with managing reference counts in the rxrpcserverkeyring function could lead to a resource leak. This vulnerability might allow a local attacker to exhaust system resources, potentially causing a denial of service DoS...

CVE-2026-31633

A flaw was found in the Linux kernel's rxrpc component. A potential integer overflow vulnerability exists in the rxgkverifyresponse function. This occurs when the tokenlen value is rounded up before a critical length check, allowing the check to be bypassed. This could potentially lead to...

CVE-2026-31631

A flaw was found in the Linux kernel, specifically within its rxrpc communication protocol. This vulnerability is a buffer overread, meaning the system attempts to read data beyond the allocated memory buffer in the rxgkdoverifyauthenticator function. This could potentially allow an attacker to...

DEBIAN-CVE-2026-31640

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