Overview
Affected versions of this package are vulnerable to Out-of-Bounds in the idpf_get_reg_intr_vecs process. An attacker can cause heap memory corruption and potentially achieve privilege escalation or kernel crash by sending a crafted VIRTCHNL2_OP_ALLOC_VECTORS reply with per-chunk num_vectors values that exceed the allocated array size.
Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
