- Summary
- CVE-2024-53126 affecting package kernel for versions less than 6.6.64.2-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
vdpa: solidrun: Fix UB bug with devres
In psnetopenpfbar() and snetopenvfbar() a string later passed to pcimiomapregions() is placed on the stack. Neither pcimiomapregions() 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().
