The vulnerability of the `btrfs_subpage_set_writeback()` function in the `fs/btrfs/subpage.c` file of the btrfs file system in the Linux operating system allows a hacker to cause a service failure.

The vulnerability of the btrfssubpagesetwriteback function in the fs/btrfs/subpage.c file of the btrfs file system in Linux kernels involves an uncontrolled and exploitable condition. Exploiting this vulnerability could allow an attacker to cause a service failure...

CVE-2026-23109

In the Linux kernel, the following vulnerability has been resolved: fs/writeback: skip ASNODATAINTEGRITY mappings in waitsbinodes Above the while loop in waitsbinodes, we document that we must wait for all pages under writeback for data integrity. Consequently, if a mapping, like fuse,...

CVE-2022-49995

The connected sources confirm CVE-2022-49995 is a Linux kernel use-after-free in writeback code when removing a disk. Specifically, wb_inode_writeback_end() could schedule work to access a freed bdi_writeback; the fix switches wb->work_lock to an irqsafe lock and checks that bdi_writeback is a...

kernel: NULL pointer dereference in udf_expand_file_adinicbdue() during writeback

A NULL pointer dereference was found in the Linux kernel’s UDF file system functionality in the way the user triggers the udffilewriteiter function for a malicious UDF image. This flaw allows a local user to crash the system...
