Lifecycle Timeline
3Description
In the Linux kernel, the following vulnerability has been resolved: cifs: fix potential use-after-free bugs in TCP_Server_Info::hostname TCP_Server_Info::hostname may be updated once or many times during reconnect, so protect its access outside reconnect path as well and then prevent any potential use-after-free bugs.
Analysis
In the Linux kernel, the following vulnerability has been resolved:
cifs: fix potential use-after-free bugs in TCP_Server_Info::hostname
TCP_Server_Info::hostname may be updated once or many times during reconnect, so protect its access outside reconnect path as well and then prevent any potential use-after-free bugs.
Technical Context
A use-after-free vulnerability occurs when a program continues to use a pointer after the referenced memory has been freed, leading to undefined behavior.
Remediation
Use memory-safe languages. Implement proper object lifecycle management. Use static and dynamic analysis tools to detect UAF patterns.
