FFS - F File System This is a cli tool for searching files like grep that does not use the OS kernel to read files, but reads your disks directly. It is practically useless, but insanely cool. this is just 1.5k lines of C code that: requires sudo only when reading a raw device node e.g. /dev/rdis...

CVE-2026-98245

A flaw was found in the Linux kernel's Btrfs file system. A local user could exploit this vulnerability to cause a Denial of Service DoS or potentially escalate privileges. The issue occurs due to missing synchronization during device replacement operations, where a concurrent transaction commit...

CVE-2026-98244

A flaw was found in the Linux kernel's Btrfs file system. When an error occurs while rebuilding the free space tree, the kernel fails to properly reset an internal state flag on failure paths. A local user could exploit this condition during filesystem operations, leaving the flag set on an activ...

CVE-2026-98279

A flaw was found in the Linux kernel's Btrfs file system. A local user can cause a denial of service DoS by enabling file verification fsverity on a subvolume that exceeds its quota or storage space limits. When the operation fails due to insufficient space, the clean-up process fails to acquire...

CVE-2026-98269

A flaw was found in the Linux kernel's Btrfs file system. When operations such as hole punching or file cloning encounter an error while updating file metadata, the kernel does not abort the active transaction. A local user could trigger these operations, potentially causing partially updated fil...
