02 May 2025 — In the Linux kernel, the following vulnerability has been resolved: scsi: core: Fix a procfs host directory removal regression scsi_proc_hostdir_rm() decreases a reference counter and hence must only be called once per host that is removed. This change does not require a scsi_add_host_with_dma() change since scsi_add_host_with_dma() will return 0 (success) if scsi_proc_host_add() is called.

02 May 2025 — In the Linux kernel, the following vulnerability has been resolved: nvmet: avoid potential UAF in nvmet_req_complete() An nvme target ->queue_response() operation implementation may free the request passed as argument. Such implementation potentially could result in a use after free of the request pointer when percpu_ref_put() is called in nvmet_req_complete(). Avoid such problem by using a local variable to save the sq pointer before calling __nvmet_req_complete(), thus avoiding dereferencing the req point... • https://git.kernel.org/stable/c/a07b4970f464f13640e28e16dad6cfa33647cc99 •

02 May 2025 — In the Linux kernel, the following vulnerability has been resolved: i40e: Fix kernel crash during reboot when adapter is in recovery mode If the driver detects during probe that firmware is in recovery mode then i40e_init_recovery_mode() is called and the rest of probe function is skipped including pci_set_drvdata().
