CVE-2024-53126 Details
Description
In the Linux kernel, the following vulnerability has been resolved: vdpa: solidrun: Fix UB bug with devres In psnet_open_pf_bar() and snet_open_vf_bar() a string later passed to pcim_iomap_regions() is placed on the stack. Neither pcim_iomap_regions() nor the functions it calls copy that string. Should the string later ever be used, this, consequently, causes undefined behavior since the stack frame will by then have disappeared. Fix the bug by allocating the strings on the heap through devm_kasprintf().
A vulnerability causing undefined behavior has been identified in the Linux kernel's virtio VDPA SolidRun driver, specifically within the functions 'psnet_open_pf_bar()' and 'snet_open_vf_bar()'. The issue arises because a string intended for 'pcim_iomap_regions()' is initially placed on the stack without being copied, leading to potential misuse once the stack frame is gone. This vulnerability affects Linux kernel versions 6.3 and prior.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been addressed. The fixed version is included in the official Linux kernel repositories.
