CVE-2025-38241

In the Linux kernel, the following vulnerability has been resolved: mm/shmem, swap: fix softlockup with mTHP swapin Following softlockup can be easily reproduced on my test machine with: echo always /sys/kernel/mm/transparenthugepage/hugepages-64kB/enabled swapon /dev/zram0 zram0 is a 48G swap...

CVE-2025-38241

CVE-2025-38241 affects the Linux kernel in mm/shmem and swap paths, causing a soft lockup with mTHP swapin due to a conflict between readahead-ordered folios in swap cache and the swapin folio allocation. The issue occurs when a 10G swap device (e.g., zram) is used with THP and cgroup memory limi...
