CVE-2026-53017

A flaw was found in the Linux kernel's f2fs filesystem. This vulnerability can lead to data loss when a file synchronization fsync operation on a newly created file occurs at the same time as a checkpoint operation. The system incorrectly assumes that a checkpoint has completed, which can result ...

SUSE CVE-2026-53017

In the Linux kernel, the following vulnerability has been resolved: f2fs: fix data loss caused by incorrect use of natentry flag Data loss can occur when fsync is performed on a newly created file before any checkpoint has been written concurrently with a checkpoint operation. The scenario is as...

SUSE CVE-2026-53018

In the Linux kernel, the following vulnerability has been resolved: f2fs: avoid reading already updated pages during GC We found the following issue during fuzz testing: page: refcount:3 mapcount:0 mapping:00000000b6e89c65 index:0x18b2dc pfn:0x161ba9 memcg:f8ffff800e269c00 aops:f2fsmetaaops ino:2...

CVE-2026-53018

A flaw was found in the Linux kernel's f2fs filesystem. During garbage collection, a race condition can occur when a page is moved and updated, but the system attempts to read it again from an outdated location. This can trigger a kernel bug, leading to a system crash and a denial of service DoS....
