Unsafe handling in bt_conn_tx_processor causes a use-after-free, resulting in a write-before-zero. The written 4 bytes are attacker-controlled, enabling precise memory corruption.

A vulnerability was identified in the handling of Bluetooth Low Energy (BLE) fixed channels (such as SMP or ATT). Specifically, an attacker could exploit a flaw that causes the BLE target (i.e., the device under attack) to attempt to disconnect a fixed channel, which is not allowed per the Bluetooth specification. This leads to undefined behavior, including potential assertion failures, crashes, or memory corruption, depending on the BLE stack implementation.

The function responsible for handling BLE connection responses does not verify whether a response is expected—that is, whether the device has initiated a connection request. Instead, it relies solely on identifier matching.

The function dns_copy_qname in dns_pack.c performs performs a memcpy operation with an untrusted field and does not check if the source buffer is large enough to contain the copied data.

When the Global Pointer (GP) relative addressing is enabled (CONFIG_RISCV_GP=y), the gp reg points at 0x800 bytes past the start of the .sdata section which is then used by the linker to relax accesses to global symbols.
