Detailsinfo

A vulnerability classified as problematic has been found in Linux Kernel up to 6.1.58/6.5.6 (Operating System). This affects some unknown processing of the component mana. The manipulation with an unknown input leads to a injection vulnerability. CWE is classifying the issue as CWE-74. The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. The impact remains unknown. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: net: mana: Fix TX CQE error handling For an unknown TX CQE error type (probably from a newer hardware), still free the SKB, update the queue tail, etc., otherwise the accounting will be wrong. Also, TX errors can be triggered by injecting corrupted packets, so replace the WARN_ONCE to ratelimited error logging.
