{"id":"CVE-2024-26790","summary":"dmaengine: fsl-qdma: fix SoC may hang on 16 byte unaligned read","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndmaengine: fsl-qdma: fix SoC may hang on 16 byte unaligned read\n\nThere is chip (ls1028a) errata:\n\nThe SoC may hang on 16 byte unaligned read transactions by QDMA.\n\nUnaligned read transactions initiated by QDMA may stall in the NOC\n(Network On-Chip), causing a deadlock condition. Stalled transactions will\ntrigger completion timeouts in PCIe controller.\n\nWorkaround:\nEnable prefetch by setting the source descriptor prefetchable bit\n( SD[PF] = 1 ).\n\nImplement this workaround.","modified":"2026-04-02T10:06:00.568162Z","published":"2024-04-04T08:20:21.742Z","related":["SUSE-SU-2024:1490-1","SUSE-SU-2024:1659-1","SUSE-SU-2024:1663-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/26xxx/CVE-2024-26790.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/106c1ac953a66556ec77456c46e818208d3a9bce"},{"type":"WEB","url":"https://git.kernel.org/stable/c/237ecf1afe6c22534fa43abdf2bf0b0f52de0aaa"},{"type":"WEB","url":"https://git.kernel.org/stable/c/518d78b4fac68cac29a263554d7f3b19da99d0da"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5b696e9c388251f1c7373be92293769a489fd367"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9d739bccf261dd93ec1babf82f5c5d71dd4caa3e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ad2f8920c314e0a2d9e984fc94b729eca3cda471"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bb3a06e9b9a30e33d96aadc0e077be095a4f8580"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/06/msg00017.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/26xxx/CVE-2024-26790.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-26790"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"b092529e0aa09829a6404424ce167bf3ce3235e2"},{"fixed":"518d78b4fac68cac29a263554d7f3b19da99d0da"},{"fixed":"bb3a06e9b9a30e33d96aadc0e077be095a4f8580"},{"fixed":"106c1ac953a66556ec77456c46e818208d3a9bce"},{"fixed":"237ecf1afe6c22534fa43abdf2bf0b0f52de0aaa"},{"fixed":"5b696e9c388251f1c7373be92293769a489fd367"},{"fixed":"ad2f8920c314e0a2d9e984fc94b729eca3cda471"},{"fixed":"9d739bccf261dd93ec1babf82f5c5d71dd4caa3e"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-26790.json"}}],"schema_version":"1.7.5"}
