Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: iouring/rw: fixed the omission of the NOWAIT check for ODIRECT write operations. When iouring initiates a write operation, it calls kiocbstartwrite, which triggers the super block rwsem. This prevents any freezes from occurring...

kernel: Linux kernel: Denial of Service due to file descriptor leak in io_uring with ocfs2

A flaw was found in the Linux kernel. A local user can exploit a file descriptor leak in the iouring subsystem when performing operations on filesystems that do not support nowait buffered read, such as ocfs2. This vulnerability occurs because a file descriptor fget is acquired but not properly...
