CVE-2026-46000 Details
Description
In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix conn-level packet handling to unshare RESPONSE packets The security operations that verify the RESPONSE packets decrypt bits of it in place - however, the sk_buff may be shared with a packet sniffer, which would lead to the sniffer seeing an apparently corrupt packet (actually decrypted). Fix this by handing a copy of the packet off to the specific security handler if the packet was cloned.
A vulnerability in the Linux kernel's RxRPC implementation could lead to a packet sniffer observing decrypted RESPONSE packets as corrupt. This issue arises because the decryption process modifies the packet in place, potentially allowing a shared sk_buff to be intercepted by a sniffer. The vulnerability affects the Linux kernel stable tree, specifically in the RxRPC connection-level packet processing.
The vulnerability has been addressed in the Linux kernel. Users should upgrade to the latest version where this issue has been fixed.
