CVE-2026-90308

CVE-2026-90308 is a use-after-free race condition in the Linux kernel's RDMA/erdma subsystem. AE QP fatal events and iWARP CM paths load queue pairs from dev->qp_xa and then reference them outside the xarray lock, while erdma_destroy_qp() can concurrently free those QP resources. The fix intro...

CVE-2026-90252

CVE-2026-90252 is a memory and socket-reference leak in the Linux kernel's Bluetooth MGMT subsystem. The root cause is that mgmt_hci_cmd_sync() queues a pending HCI command with a NULL destroy callback , meaning a cancelled entry is never freed. When a controller is unregistered, hci_cmd_sync_cle...

CVE-2026-90236 NFSD: Release the export reference when reaping open stateids

In the Linux kernel, the following vulnerability has been resolved: NFSD: Release the export reference when reaping open stateids nfs4putstid releases the svcexport tracked in nfs4stid.scexport, but freeolstateidreaplist frees open and lock stateids by calling -scfree directly, bypassing that pat...

CVE-2026-90236

CVE-2026-90236 affects the Linux kernel NFSD (NFS server daemon). The bug is a reference-counting flaw in NFSv4 state ID teardown: free_ol_stateid_reaplist() frees open and lock stateids via ->sc_free() without releasing the svc_export reference, unlike nfs4_put_stid(). This pins the export an...
