Summary

In the Linux kernel ESPINTCP subsystem, a vulnerability exists related to partial sends. Using sk_msg_free_partial() ensures skmsg consistency in each iteration, simplifying code and fixing bugs in skmsg accounting when not sending the full contents.

Risk Assessment

Accounting errors could lead to incorrect ESPINTCP protocol behavior, potentially causing data loss or crashes.

Recommendation

Apply a kernel update containing the fix that uses sk_msg_free_partial() for partial send handling.

Original NVD description (English source)

In the Linux kernel, the following vulnerability has been resolved: espintcp: use sk_msg_free_partial to fix partial send sk_msg_free_partial() ensures consistency of the skmsg at every iteration, without having to manually handle uncharges and offsets. This simplifies the code, and fixes some bugs in skmsg accounting when we don't send the full contents.
