Linux Kernel Security Vulnerabilities

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 rxgkverifyresponse function’s rounding of the tokenlen value before checking it. This roundin...

CVE-2026-31635: Improper Handling of Length Parameter Inconsistency

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...
