AI-suggested
An official patch is available and should be applied to affected linux-hwe-edge kernel versions to remediate this vulnerability. Users should update their systems to the fixed kernel versions as provided by their distribution vendors. No additional mitigation steps are indicated by the vendor advisory.
Description
A vulnerability in the Linux kernel's uprobes/x86 subsystem was fixed by ensuring the proper use of the mm_struct pointer in the __in_uprobe_trampoline function. The issue involved incorrect use of current->mm for VMA lookup during the unregister path, which is incorrect because the tracer context differs from the traced process context. This flaw was addressed by adding an mm_struct pointer argument to the function and updating callers accordingly. The vulnerability affects specific linux-hwe-edge kernel versions and has a CVSS score of 7.8, indicating a high impact on confidentiality, integrity, and availability. A patch is available to remediate the issue.
