CVE-2022-49701 scsi: ibmvfc: Allocate/free queue resource only during probe/remove

In the Linux kernel, the following vulnerability has been resolved: scsi: ibmvfc: Allocate/free queue resource only during probe/remove Currently, the sub-queues and event pool resources are allocated/freed for every CRQ connection event such as reset and LPM. This exposes the driver to a couple...

CVE-2022-49701

CVE-2022-49701 affects the Linux kernel ibmvfc SCSI driver. The issue arises because sub-queues and event pool resources were allocated/freed for every CRQ connection event (e.g., reset, LPM) instead of only during probe/remove, creating a race window and potential list corruption when queues are...

CVE-2022-49646

CVE-2022-49646 affects the Linux kernel’s wifi/mac80211 code. When using iTXQ, the queue-selection logic assumed a single broadcast vif queue (BE). Allowing non-BE queue markings breaks that assumption and can break txq->ac == skb_queue_mapping, impacting queue handling in the driver and poten...

CVE-2022-49622

CVE-2022-49622 (Linux kernel) describes a use-after-free risk in nf_tables when verdict is NF_STOLEN in netfilter, where skb freeing may have occurred. The fix prevents illegal skb access by: (1) caching skb->nf_trace in the trace state and refreshing it when verdict != STOLEN; (2) skipping sk...
