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-2026-98960

A flaw was found in the Linux kernel's Btrfs file system. When handling asynchronous input/output I/O requests through the iouring subsystem, allocated memory is not properly released if an operation encounters a retry condition and is canceled before completion. A local user could exploit this...

CVE-2026-98962

A flaw was found in the Linux kernel's Btrfs file system. When an encoded read operation initiated through iouring fails, the kernel fails to release the allocated memory buffer. A local user could exploit this flaw by repeatedly submitting failing read requests, causing a memory leak that can le...

CVE-2026-98961

A flaw was found in the Linux kernel's Btrfs file system. A local attacker can cause a Denial of Service DoS by triggering error conditions during asynchronous read operations. When an iouring read request fails, such as during a memory allocation failure, the kernel does not release acquired...

CVE-2026-98963

A flaw was found in the Btrfs file system within the Linux kernel. During asynchronous read operations, an early I/O error can cause both the direct and deferred error handling paths to release the same resources. This double-free condition can be exploited by a local user to corrupt memory and...
