SUSE CVE-2021-47649
In the Linux kernel, the following vulnerability has been resolved: udmabuf: validate ubuf-pagecount Syzbot has reported GPF in sgallocappendtablefrompages. The problem was in ubuf-pages == ZEROPTR. ubuf-pagecount is calculated from arguments passed from user-space. If user creates udmabuf with...
SUSE CVE-2022-49055
In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Check for potential null return of kmallocarray As the kmallocarray may return null, the 'eventwaitersi.wait' would lead to null-pointer dereference. Therefore, it is better to check the return value of kmallocarray t...

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 the possibility that kmallocarray may return a null pointer, resulting in a null pointer dereference...
Astra Linux – Vulnerability in Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: powerpc/pseries: Fixed dtlaccesslock to use a rwsemaphore. The dtlaccesslock needs to be a rwsemaphore, a sleeping lock, because the code calls kmalloc while holding this lock, which can cause a sleep condition. bash echo 1...
