UBUNTU-CVE-2024-41012

In the Linux kernel, the following vulnerability has been resolved: filelock: Remove locks reliably when fcntl/close race is detected When fcntlsetlk races with close, it removes the created lock with dolockfilewait. However, LSMs can allow the first dolockfilewait that created the lock while...

CVE-2024-41012

In the Linux kernel, CVE-2024-41012 pertains to a fcntl/close race in file locking where an LSM could allow the first do_lock_file_wait() to acquire a lock while denying the second removal, and POSIX lock removal could fail due to GFP_KERNEL allocation during range splitting. The issue can lead t...

runc: file descriptor leak

A file descriptor leak issue was found in the runc package. While a user performs OCLOEXEC all file descriptors before executing the container code, the file descriptor is open when performing setcwd2, which means that the reference can be kept alive in the container by configuring the working...

CVE-2024-40900

In the Linux kernel, the following vulnerability has been resolved: cachefiles: remove requests from xarray during flushing requests Even with CACHEFILESDEAD set, we can still read the requests, so in the following concurrency the request may be used after it has been freed: mount | daemonthread1...

kernel: tls: race between async notify and socket close

A race condition vulnerability was found in the tls subsystem of the Linux kernel. The submitting thread that calls recvmsg/sendmsg may exit as soon as the async crypto handler calls complete; any code past that point risks touching already freed data. This could lead to a use-after-free issue an...

kernel: tls: race between tx work scheduling and socket close

A race condition vulnerability was found in the tls subsystem of the Linux kernel. The submitting thread recvmsg/sendmsg may exit as soon as the async crypto handler calls complete, which could lead to undefined behavior and a denial of service...
