CVE-2026-98071

/// Technical description

In the Linux kernel, the following vulnerability has been resolved:

net/rds: clear cp_flags bits individually in rds_conn_path_reset()

rds_conn_path_reset() wipes the whole flag word with a plain

cp->cp_flags = 0 store. Every other accessor of that word uses

atomic bitops, and some of them can run concurrently with the reset:

RDS_LL_SEND_FULL is set from rds_send_xmit() and cleared from the

transport completion paths, neither of which holds anything that

excludes the shutdown worker. A plain store racing an atomic

read-modify-write on the same word is a data race, and whichever

side loses has its update silently discarded.

Clear the two bits the reset is actually responsible for instead.

RDS_IN_XMIT and RDS_RECV_REFILL need no store at all here: they

belong to the caller, rds_conn_shutdown(), which waits for both to be

clear before calling the transport shutdown and this reset.

This also gives every bit in cp_flags a single well-defined writer

discipline, which the following patc
