CVE-2021-38203

A flaw was found in the btrfs filesystem in the Linux kernel that allows attackers to cause a denial of service via processes that trigger allocation of new system chunks when there is a shortage of free space in the system spaceinfo. The highest threat from this vulnerability is to system...

Linux kernel denial-of-service vulnerability (CNVD-2021-60518)

Linux kernel is the kernel used by the Linux Foundation's open source operating system Linux. Linux kernel is vulnerable due to a deadlock flaw in btrfs when there is not enough free space in system spaceinfo. A local attacker can exploit this vulnerability to cause a denial of service situation...
