Summary
Red Hat Security Advisory: kernel-rt security update
Notes
Topic
An update for kernel-rt is now available for Red Hat Enterprise Linux 9.0 Update Services for SAP Solutions.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.
Security Fix(es):
* kernel: netfilter: nf_tables: disallow anonymous set with timeout flag (CVE-2024-26642)
* kernel: netfilter: nft_chain_filter: handle NETDEV_UNREGISTER for inet/ingress basechain (CVE-2024-26808)

napi_enable() are called.\nIf there are 4 queues and only 3 queues are used for the current\nconfiguration, only 3 queues\u0027 napi should be registered and enabled.\nThe ionic_qcq_enable() checks whether the .poll pointer is not NULL for\nenabling only the using queue\u0027 napi. Unused queues\u0027 napi will not be\nregistered by netif_napi_add(), so the .poll pointer indicates NULL.\nBut it couldn\u0027t distinguish whether the napi was unregistered or not\nbecause netif_napi_del() doesn\u0027t reset the .poll pointer to NULL.\nSo, ionic_qcq_enable() calls napi_enable() for the queue, which was\nunregistered by netif_napi_del().\n\nReproducer:\n ethtool -L
