{"id":"CVE-2023-52594","summary":"wifi: ath9k: Fix potential array-index-out-of-bounds read in ath9k_htc_txstatus()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: ath9k: Fix potential array-index-out-of-bounds read in ath9k_htc_txstatus()\n\nFix an array-index-out-of-bounds read in ath9k_htc_txstatus(). The bug\noccurs when txs-\u003ecnt, data from a URB provided by a USB device, is\nbigger than the size of the array txs-\u003etxstatus, which is\nHTC_MAX_TX_STATUS. WARN_ON() already checks it, but there is no bug\nhandling code after the check. Make the function return if that is the\ncase.\n\nFound by a modified version of syzkaller.\n\nUBSAN: array-index-out-of-bounds in htc_drv_txrx.c\nindex 13 is out of range for type '__wmi_event_txstatus [12]'\nCall Trace:\n ath9k_htc_txstatus\n ath9k_wmi_event_tasklet\n tasklet_action_common\n __do_softirq\n irq_exit_rxu\n sysvec_apic_timer_interrupt","modified":"2026-05-18T05:56:51.801902227Z","published":"2024-03-06T06:45:25.071Z","related":["ALSA-2024:3618","SUSE-SU-2024:1466-1","SUSE-SU-2024:1480-1","SUSE-SU-2024:1490-1","SUSE-SU-2024:2892-1","SUSE-SU-2024:2901-1","SUSE-SU-2024:2940-1","USN-6818-2","USN-6819-2"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/52xxx/CVE-2023-52594.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/25c6f49ef59b7a9b80a3f7ab9e95268a1b01a234"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2adc886244dff60f948497b59affb6c6ebb3c348"},{"type":"WEB","url":"https://git.kernel.org/stable/c/84770a996ad8d7f121ff2fb5a8d149aad52d64c1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9003fa9a0198ce004b30738766c67eb7373479c9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/be609c7002dd4504b15b069cb7582f4c778548d1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e4f4bac7d3b64eb75f70cd3345712de6f68a215d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f11f0fd1ad6c11ae7856d4325fe9d05059767225"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f44f073c78112ff921a220d01b86d09f2ace59bc"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/06/msg00017.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/06/msg00020.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/52xxx/CVE-2023-52594.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-52594"},{"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":"27876a29de221186c9d5883e5fe5f6da18ef9a45"},{"fixed":"f44f073c78112ff921a220d01b86d09f2ace59bc"},{"fixed":"f11f0fd1ad6c11ae7856d4325fe9d05059767225"},{"fixed":"84770a996ad8d7f121ff2fb5a8d149aad52d64c1"},{"fixed":"9003fa9a0198ce004b30738766c67eb7373479c9"},{"fixed":"25c6f49ef59b7a9b80a3f7ab9e95268a1b01a234"},{"fixed":"e4f4bac7d3b64eb75f70cd3345712de6f68a215d"},{"fixed":"be609c7002dd4504b15b069cb7582f4c778548d1"},{"fixed":"2adc886244dff60f948497b59affb6c6ebb3c348"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-52594.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.0.0"},{"fixed":"4.19.307"}]},{"type":"ECOSYSTEM","events":[{"introduced":"4.20.0"},{"fixed":"5.4.269"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.5.0"},{"fixed":"5.10.210"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.149"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.77"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.16"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.7.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-52594.json"}}],"schema_version":"1.7.5"}
