CyberRota Analysis
AI-GeneratedA use-after-free vulnerability exists in the Linux kernel's SMB client due to the improper handling of the `tgthint` pointer in the `free_tgts()` function, which can lead to potential exploitation if accessed after the associated structures have been freed. This flaw could allow an attacker to execute arbitrary code or cause a denial of service, particularly affecting systems that rely on SMB for file sharing. Linux administrators and security teams should prioritize patching this vulnerability to mitigate risks associated with their SMB implementations.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: smb: client: clear ce->tgthint in free_tgts() When free_tgts() frees all structures in ce->tlist, ce->tgthint is left pointing to one of the freed cache_dfs_tgt structures. If ce->tgthint is not reset before it is used later, it results in a use-after-free. Set ce->tgthint to NULL in free_tgts() after the elements are freed to reflect that no elements remain.
