Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
accel/qaic: Add overflow check to remap_pfn_range during mmap<br />
<br />
The call to remap_pfn_range in qaic_gem_object_mmap is susceptible to<br />
(re)mapping beyond the VMA if the BO is too large. This can cause use<br />
after free issues when munmap() unmaps only the VMA region and not the<br />
additional mappings. To prevent this, check the remaining size of the<br />
VMA before remapping and truncate the remapped length if sg->length is<br />
too large.<br />
<br />
