the Linux kernel, the following vulnerability has been resolved:\n\nrxrpc: Fix the ACK parser to extract the SACK table for parsing\n\nFix modification of the received skbuff in rxrpc_input_soft_acks() and a\npotential incorrect access of the buffer in a fragmented UDP packet (the\npacket would probably have to be deliberately pre-generated as fragmented)\nwhen AF_RXRPC tries to extract the contents of the SACK table by copying\nout the contents of the SACK table into a buffer before attempting to parse\n\nAF_RXRPC assumes that it can just call skb_condense() and then validly\naccess the SACK table from skb->data and that it will be a flat buffer -\nbut skb_condense() can silently fail to do anything under some\ncircumstances.\n\nNote that whilst rxrpc_input_soft_acks() should be able to parse extended\nACKs, the rest of AF_RXRPC doesn't currently support that.\n\nFurther, there's then no need to call skb_condense() in rxrpc_input_ack(),\nso don't.","published_at":"2026-06-25T08:38:36.187000Z","last_modified_at":null,"cvss_v3_score":9.8,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","cvss_v3_severity":"CRITICAL","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":null,"nvd_references":["https://git.kernel.org/stable/c/566c4c1244de50fbff1f89ff93c9d7b0fc256db4","https://git.kernel.org/stable/c/224298450be5c04d2a6ea1c2a94669d7ebf65d00","https://git.kernel.org/stable/c/333b6d5bb9f87827ac2639c737bf9613dbae7253"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-28T17:55:28.590503Z","updated_at":"2026-06-28T23:30:50.753831Z"},"effective_severity":"CRITICAL","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack
