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, which stems from a post-release use in the gpiolib:cdev module lineinfochangednotify...

CVE-2024-36898: Use of Uninitialized Resource

In the Linux kernel, the following vulnerability has been resolved: gpiolib: cdev: fix uninitialised kfifo If a line is requested with debounce, and that results in debouncing in software, and the line is subsequently reconfigured to enable edge detection then the allocation of the kfifo to conta...

CVE-2024-36932: Use After Free

In the Linux kernel, the following vulnerability has been resolved: thermal/debugfs: Prevent use-after-free from occurring after cdev removal Since thermaldebugcdevremove does not run under cdev-lock, it can run in parallel with thermaldebugcdevstateupdate and it may free the struct thermaldebugf...

kernel: gpiolib: cdev: fix NULL-pointer dereferences

In the Linux kernel, the following vulnerability has been resolved: gpiolib: cdev: fix NULL-pointer dereferences There are several places where we can crash the kernel by requesting lines, unbinding the GPIO device, then calling any of the system calls relevant to the GPIO character device's...
