In drivers/pci/hotplug/rpadlpar_sysfs.c in the Linux kernel through 5.11.8, the RPA PCI Hotplug driver has a user-tolerable buffer overflow when writing a new device name to the driver from userspace, allowing userspace to write data to the kernel stack frame directly. This occurs because add_slot_store and remove_slot_store mishandle drc_name '\0' termination, aka CID-cc7a0bb058b8. Linux Kernel Exists in a classic buffer overflow vulnerability. Vendor exploits this vulnerability CID-cc7a0bb058b8 It is published as.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. Pillow is a Python-based image processing library. There is currently no information about this vulnerability, please feel free to follow CNNVD or manufacturer announcements. ========================================================================== Ubuntu Security Notice USN-5343-1 March 22, 2022 linux, linux-aws, linux-kvm, linux-lts-xenial vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 16.04 ESM - Ubuntu 14.04 ESM Summary: Several security issues were fixed in the Linux kernel.

A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-3483) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 20.04 LTS: linux-image-5.10.0-1026-oem 5.10.0-1026.27 linux-image-oem-20.04b 5.10.0.1026.27 After a standard system update you need to reboot your computer to make all the necessary changes. ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
