Linux kernel security vulnerabilities

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from a race condition between sockmapclose and skpsockput in the sockmap component...

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...

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...
