A flaw was found in the Linux kernel. A check was not done on the alloc_workqueue return value of the iwl_trans_pcie_alloc function potentially leading to a NULL pointer dereference. This error condition could lead to a denial of service. The highest threat from this vulnerability is to system availability.

Created kernel tracking bugs for this issue: Affects: fedora-all [bug 1760442] This was fixed for Fedora with the 5.4 kernel rebases. Upstream fix: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=8188a18ee2e48c9a7461139838048363bfce3fef Statement: This issue is rated as having Low impact because of the preconditions needed to trigger the error/resource cleanup code path (system-wide out-of-memory condition, high privileges or physical access). The attacker would have to be able to induce system-wide out-of-memory condition which itself could be seen as a local denial of service. It could be argued that having such privileges has the same impact as the flaw itself. Mitigation: Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
