CVE-2026-98226

The Linux kernel contains a vulnerability where the SWAP_USAGE_OFFLIST_BIT collides with the real usage count because it is defined as bit 30 of an atomic_t type. On systems with 4 KiB pages, this collision occurs once the count reaches 4 TiB . This leads to several issues: /proc/swaps understate...
