CVE-2026-93080 firmware: arm_scmi: Fix transport device teardown lookup

In the Linux kernel, the following vulnerability has been resolved: firmware: armscmi: Fix transport device teardown lookup SCMI transport devices are deliberately excluded from normal SCMI bus matching so protocol drivers cannot bind to the internal transport children. However, scmidevicedestroy...

CVE-2026-93081

CVE-2026-93081 affects the Linux kernel 's firmware: arm_scmi driver, specifically the SCMI device destroy path. The root cause is that scmi_child_dev_find() drops the reference returned by device_find_child() before returning the scmi_device pointer, so a concurrent unregister can release the de...

CVE-2026-93079

CVE-2026-93079 is a heap out-of-bounds write in the Linux kernel's CXL subsystem. In cxlctl_get_feature(), the output buffer is sized from the user-supplied fwctl_rpc.out_len, but the device is instructed to write cxl_mbox_get_feat_in.count bytes into that buffer. Because count is a separate user...

CVE-2026-93078 cxl/features: Reject Set Features output buffer smaller than the header

In the Linux kernel, the following vulnerability has been resolved: cxl/features: Reject Set Features output buffer smaller than the header cxlctlsetfeature sizes its output buffer from the user's fwctlrpc.outlen but never checks it is large enough to hold even the fwctlrpccxlout header. With...

CVE-2026-93078

CVE-2026-93078 is a vulnerability in the Linux kernel 's cxl/features subsystem. The function cxlctl_set_feature() sizes its output buffer from the user-supplied fwctl_rpc.out_len without verifying it is large enough to hold the fwctl_rpc_cxl_out header. When out_len is zero, kvzalloc() returns Z...
