CVE-2026-93104 in Linux
Riassunto
di MITRE • 18/09/2026
In the Linux kernel, the following vulnerability has been resolved:
RDMA/rvt: Return NULL after port allocation failure
rvt_alloc_device() deallocates the IB device when its port array cannot be allocated but then returns the pointer to the released allocation. Callers treat any non-NULL value as valid and dereference it, resulting in a use-after-free.
Return NULL immediately after deallocation so callers can propagate the allocation failure.
Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
