CVE-2022-49923
The CVE affects the Linux kernel nxp-nci path (nfc: nxp-nci: Fix potential memory leak in nxp_nci_send). The root cause is that nxp_nci_send() frees the allocated skb only on nxp_nci_i2c_write() failure; when the write succeeds, nxp_nci_i2c_write() does not free the skb, causing a memory leak. A ...

CVE-2022-49896
CVE-2022-49896 relates to the Linux kernel’s cxl/pmem subsystem. The issue: when a cxl_nvdimm object is removed, associated regions were not consistently disabled, because the driver tracked only one region per nvdimm device. This could leak regions and cause cxl_memdev reference leaks. The vulne...
