17 Apr 2024 — In the Linux kernel, the following vulnerability has been resolved: aoe: fix the potential use-after-free problem in aoecmd_cfg_pkts This patch is against CVE-2023-6270. The description of cve is: A flaw was found in the ATA over Ethernet (AoE) driver in the Linux kernel. The aoecmd_cfg_pkts() function improperly updates the refcnt on `struct net_device`, and a use-after-free can be triggered by racing between the free on the struct and the access through the `skbtxq` global queue.

CVE-2024-26872 – RDMA/srpt: Do not register event handler until srpt device is fully setup

17 Apr 2024 — In the Linux kernel, the following vulnerability has been resolved: RDMA/srpt: Do not register event handler until srpt device is fully setup Upon rare occasions, KASAN reports a use-after-free Write in srpt_refresh_port(). This seems to be because an event handler is registered before the srpt device is fully setup and a race condition upon error may leave a partially setup event handler in place. Instead, only register the event handler after srpt device initialization is complete.

CVE-2024-26846 – nvme-fc: do not wait in vain when unloading module

17 Apr 2024 — In the Linux kernel, the following vulnerability has been resolved: nvme-fc: do not wait in vain when unloading module The module exit path has race between deleting all controllers and freeing 'left over IDs'. To prevent double free a synchronization between nvme_delete_ctrl and ida_destroy has been added by the initial commit. There is some logic around trying to prevent from hanging forever in wait_for_completion, though it does not handling all cases.
