kernel: mptcp: fix race condition in mptcp_schedule_work()
A race in mptcpschedulework could lead to a use-after-free: the function queued work and only then acquired a reference to the socket. If the worker ran to completion immediately, the subsequent sockhold operated on a freed object. Impact ranges from kernel crash DoS to potential privilege...
kernel: Linux kernel: Denial of Service in ATM CLIP module via infinite recursion
A flaw was found in the Linux kernel's Asynchronous Transfer Mode ATM Classical IP CLIP module. A local user can trigger an infinite recursive call in the clippush function by repeatedly calling the ioctlATMARPMKIP system call. This vulnerability occurs when the socket is closed, leading to stack...
Linux Kernel Security Vulnerabilities
The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from improper handling of inittask errors, and could potentially lead to a kernel crash...
kernel: Linux kernel (CIFS): Use-after-free vulnerability allows data integrity compromise and denial of service
A flaw was found in the Linux kernel's Common Internet File System CIFS component. This use-after-free vulnerability occurs due to improper handling of server hostname information during connection re-establishment. An attacker on an adjacent network could exploit this, potentially leading to a...
