CVE-2022-3524: Linux Kernel IPv6 ipv6_renew_options memory leak

Published Oct 12, 2022
·
Updated

A memory leak flaw was found in the Linux kernel’s IPv6 functionality in how a user triggers the setsockopt of the IPV6ADDRFORM and IPV6DSTOPTS type. This flaw allows a user to crash the system if the setsockopt function is being called simultaneously with the IPV6ADDRFORM type and other processes with the IPV6DSTOPTS type. This issue is unlikely to happen unless a local process triggers IPV6ADDRFORM.

Other sources

A vulnerability was found in Linux Kernel. It has been declared as problematic. Affected by this vulnerability is the function ipv6renewoptions of the component IPv6 Handler. The manipulation leads to memory leak. The attack can be launched remotely. It is recommended to apply a patch to fix this issue. The identifier VDB-211021 was assigned to this vulnerability.
