{"affected":[],"cveId":"CVE-2026-64549","cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: bpa10x: avoid OOB read of revision string in bpa10x_setup()\n\nbpa10x_setup() sends the vendor command 0xfc0e and passes the response\nto bt_dev_info() and hci_set_fw_info() as a \"%s\" string starting at\nskb->data + 1, without checking the length:\n\n\tbt_dev_info(hdev, \"%s\", (char *)(skb->data + 1));\n\thci_set_fw_info(hdev, \"%s\", skb->data + 1);\n\nA device that returns a one-byte response (status only) leaves\nskb->data + 1 past the end of the data, and the %s walk reads adjacent\nslab memory until it meets a NUL. The same happens when the payload is\nnot NUL-terminated within skb->len. The out-of-bounds bytes end up in\nthe kernel log and the firmware-info debugfs file.\n\nPrint the revision string with a bounded \"%.*s\" limited to skb->len - 1\ninstead. This keeps the string readable for well-behaved devices while\nnever reading past the received data, and does not fail setup, so a\ndevice returning a short or unterminated response keeps working.","epss":null,"exploits":[],"kev":null,"metrics":[],"modifiedAt":1793729739353,"publishedAt":1785187027720,"references":[{"source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":[],"url":"https://git.kernel.org/stable/c/1813add71e386f77b3040e6c8dc9b7b3ff965a6c"},{"source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":[],"url":"https://git.kernel.org/stable/c/4b4008dda1d0c6e598d7865631ad4eda63a560f0"},{"source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":[],"url":"https://git.kernel.org/stable/c/7a64f39ebe1bacd9004a62eceadac0b122ec3cc2"},{"source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":[],"url":"https://git.kernel.org/stable/c/a8e169d308775039200bb9c905c7ce420db6e8c5"},{"source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":[],"url":"https://git.kernel.org/stable/c/bd56c23f1f8681a2857ee924a8bd3abf87c8913b"},{"source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":[],"url":"https://git.kernel.org/stable/c/bfc9e7be289df11e8e38c98cd78019d67fdd0bd5"},{"source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":[],"url":"https://git.kernel.org/stable/c/dd068ef044128db655f48323a4acfd5907e04903"},{"source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":[],"url":"https://git.kernel.org/stable/c/f80b4afe893dffa9fabdbf80fb4d6782b24a6793"}],"remediation":[],"revision":"1fd2c6251683c0954b3a60587f1da6f2420e7de193d98987e37a5ccea22cfc0c","sources":[{"modifiedAt":1793729739353,"name":"NVD","retrievedAt":1793729783751,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-64549"}],"ssvc":null,"status":"published","title":"CVE-2026-64549","updatedAt":1793729783751}
