CVE-2026-98072

The Linux kernel contains a vulnerability in the net/rds component where the release_in_xmit() function fails to maintain necessary memory ordering. Specifically, it uses clear_bit_unlock() to clear RDS_IN_XMIT, which lacks the full barrier required for a subsequent load of the wait queue head. T...
