CVE-2025-38580

The CVE-2025-38580 entry concerns a Linux kernel ext4 use-after-free in ext4_end_io_rsv_work(). The fix adds a check in ext4_io_end_defer_completion() to ensure io_end->list_vec is empty before adding to i_rsv_conversion_list, preventing starting an unnecessary worker. It also adds ext4_emerge...

CVE-2025-38580 ext4: fix inode use after free in ext4_end_io_rsv_work()

In the Linux kernel, the following vulnerability has been resolved: ext4: fix inode use after free in ext4endiorsvwork In ext4ioenddefercompletion, check if ioend-listvec is empty to avoid adding an ioend that requires no conversion to the irsvconversionlist, which in turn prevents starting an...

CVE-2025-38578

CVE-2025-38578 concerns a use-after-free in the f2fs code path of the Linux kernel (f2fs_sync_inode_meta) that can occur during inode writeback, traced to a del-list path that frees an inode still in use. Syzbot reported a UAF in the f2fs_inode_synced flow, leading to a crash via KASAN. The conne...
