This causes sixpack_decode() to process bytes that\nshould have been skipped due to TTY errors.  The TTY layer does not\nguarantee that cp[i] holds a meaningful value when fp[i] is set, so\npassing those positions to sixpack_decode() results in KMSAN reporting\nan uninit-value read.\n\nFix this by processing bytes one at a time, advancing cp on each\niteration, and only passing valid (non-error) bytes to sixpack_decode().\nThis matches the pattern used by slip_receive_buf() and\nmkiss_receive_buf() for the same purpose.","published_at":"2026-06-24T16:30:22.817000Z","last_modified_at":null,"cvss_v3_score":null,"cvss_v3_vector":null,"cvss_v3_severity":null,"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/1d3abf0c3ddeefc6f6d913aa129acc06fce8240a","https://git.kernel.org/stable/c/d4cceb5184538613572fb79319453f281b1eeacb","https://git.kernel.org/stable/c/2951656b0de00153f2687f3a093890bce72b6215","https://git.kernel.org/stable/c/e9cf4018d74237d142cd66243c821d13593270f0","https://git.kernel.org/stable/c/d9ce2a4b679122397d7f35bad7be46913ad1ca80","https://git.kernel.org/stable/c/987af7625ceb1ee59d70eb0abd7af11c75e45d79","https://git.kernel.org/stable/c/578f3aba427c938fecfa0d8c83d9acb213a9b24a","https://git.kernel.org/stable/c/bf9a38803b2626b01cc769aaf13485d8650f576f"],"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":null,"badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":null,"metrics":[]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","version_start_inclusive":true,"version_end":"1d3abf0c3ddeefc6f6d913aa129acc06fce8240a","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:1da177e4c3f41524e886b7f1b8a0c1fc7321cac2:1d3abf0c3ddeefc6f6d913aa129acc06fce8240a"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","version_start_inclusive":true,"version_end":"d4cceb5184538613572fb79319453f281b1eeacb","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:1da177e4c3f41524e886b7f1b8a0c1fc7321cac2:d4cceb5184538613572fb79319453f281b1eeacb"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","version_start_inclusive":true,"version_end":"2951656b0de00153f2687f3a093890bce72b6215","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:1da177e4c3f41524e886b7f1b8a0c1fc7321cac2:2951656b0de00153f2687f3a093890bce72b6215"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","version_start_inclusive":true,"version_end":"e9cf4018d74237d142cd66243c821d13593270f0","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:1da177e4c3f41524e886b7f1b8a0c1fc7321cac2:e9cf4018d74237d142cd66243c821d13593270f0"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","version_start_inclusive":true,"version_end":"d9ce2a4b679122397d7f35bad7be46913ad1ca80","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:1da177e4c3f41524e886b7f1b8a0c1fc7321cac2:d9ce2a4b679122397d7f35bad7be46913ad1ca80"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","version_start_inclusive":true,"version_end":"987af7625ceb1ee59d70eb0abd7af11c75e45d79","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:1da177e4c3f41524e886b7f1b8a0c1fc7321cac2:987af7625ceb1ee59d70eb0abd7af11c75e45d79"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","version_start_inclusive":true,"version_end":"578f3aba427c938fecfa0d8c83d9acb213a9b24a","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:1da177e4c3f41524e886b7f1b8a0c1fc7321cac2:578f3aba427c938fecfa0d8c83d9acb213a9b24a"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","version_start_inclusive":true,"version_end":"bf9a38803b2626b01cc769aaf13485d8650f576f","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:1da177e4c3f41524e886b7f1b8a0c1fc7321cac2:bf9a38803b2626b01cc769aaf13485d8650f576f"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"2.6.12","version_start_inclusive":true,"version_end":"2.6.12","version_end_inclusive":true,"cpe23_uri":"cve5:linux:linux:2.6.12:2.6.12"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"0","version_start_inclusive":true,"version_end":"2.6.12","version_end_inclusive":false,"cpe23_uri":"cve
