- Summary
- CVE-2026-46140 affecting package kernel for versions less than 6.6.144.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: btmtk: validate WMT event SKB length before struct access
btmtkusbhciwmtsync() casts the WMT event response SKB data to struct btmtkhciwmtevt (7 bytes) and struct btmtkhciwmtevt_funcc (9 bytes) without first checking that the SKB contains enough data. A short firmware response causes out-of-bounds reads from SKB tailroom.
Use skbpulldata() to validate and advance past the base WMT event header. For the FUNC_CTRL case, pull the additional status field bytes before accessing them.
