In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
Bluetooth: hci_event: validate LE Set CIG Parameters response<\/p>\n
The Command Complete dispatch validates only the fixed part of the LE Set
\nCIG Parameters response. After that part is pulled from the skb,
\nhci_cc_le_set_cig_params() trusts num_handles and reads each entry in the
\ntrailing handle array.<\/p>\n
Matching num_handles against the command’s num_cis does not guarantee
\nthat the response contains the advertised handles. A truncated response
\nfrom a malfunctioning controller can therefore make the handler read
\nbeyond the skb data.<\/p>\n
Validate that the remaining skb data contains all advertised handles.
\nInclude this in the existing response validation so malformed responses
\nalso follow the established CIG failure handling.<\/p>\n","protected":false},"excerpt":{"rendered":"
