CVE-2026-72217 SUNRPC: Bound-check xdr_buf_to_bvec() stores before writing

In the Linux kernel, the following vulnerability has been resolved: SUNRPC: Bound-check xdrbuftobvec stores before writing xdrbuftobvec writes a biovec into the caller's array before testing whether that slot is in range, and the head branch performs the store with no check at all. When the...

CVE-2026-72217

CVE-2026-72217 – The Linux kernel SUNRPC xdr_buf_to_bvec() path wrote a bio_vec into the caller’s array before validating the target slot, allowing an out-of-bounds write when budget is exhausted. The rq_bvec array for nfsd_vfs_write() is allocated to rq_maxpages with no slack, so an overflow cou...

CVE-2026-72150

The CVE-2026-72150 issue affects the Linux kernel sunrpc subsystem. The xprt_create_args structure was allocated on the stack without initialization in rpc_sysfs_xprt_switch_add_xprt_store(), leaving fields such as srcaddr, bc_xps, and flags with garbage data. This can cause kernel panic when xs_...
