CVE-2026-90319

CVE-2026-90319 affects the RapidIO (rio) subsystem in the Linux kernel . The root cause is a use-after-free / double-free bug: when rio_add_net() fails during device registration, rio_scan_alloc_net() releases the allocated rio_net object via put_device(), but the mport->net pointer is left da...

CVE-2026-90319 rapidio: clear mport->net when rio_add_net() fails

In the Linux kernel, the following vulnerability has been resolved: rapidio: clear mport-net when rioaddnet fails rioallocnet stores the newly allocated rionet in mport-net before rioscanallocnet registers the device. If rioaddnet fails, rioscanallocnet drops the device reference with putdevice,...

CVE-2026-90107 net/smc: free pending qentry in smc_llc_flow_stop() before memset

In the Linux kernel, the following vulnerability has been resolved: net/smc: free pending qentry in smcllcflowstop before memset smcllcflowstop resets a flow struct with a blind memset: spinlockbh&lgr-llcflowlock; memsetflow, 0, sizeofflow; flow-type = SMCLLCFLOWNONE; spinunlockbh&lgr-llcflowlock...

CVE-2026-90107

CVE-2026-90107 is a memory leak in the Linux kernel's SMC (Shared Memory Communications) module, specifically in smc_llc_flow_stop(). A blind memset zeroes the flow struct without first freeing a potentially non-NULL flow->qentry pointer. The leak is triggered when a late-arriving duplicate CO...

CVE-2026-90108

CVE-2026-90108 is a memory leak in the Linux kernel 's net/smc subsystem. When smc_llc_event_handler() transitions the local LLC flow from SMC_LLC_FLOW_REQ_ADD_LINK to SMC_LLC_FLOW_ADD_LINK, it overwrites flow->qentry via smc_llc_flow_qentry_set() without first freeing a previously stashed ent...
