- Summary
- [none]
- Details
-
gssmechfree in net/sunrpc/authgss/gssmechswitch.c in the rpcsecgsskrb5 implementation in the Linux kernel through 5.6.10 lacks certain domainrelease calls, leading to a memory leak. Note: This was disputed with the assertion that the issue does not grant any access not already available. It is a problem that on unloading a specific kernel module some memory is leaked, but loading kernel modules is a privileged operation. A user could also write a kernel module to consume any amount of memory they like and load that replicating the effect of this bug
