CVE-2026-1231995.5 MED—
——0eBook-speaker 6.1.0 through 6.2.0 contains a stack buffer overflow vulnerability in get_attributes() in src/common.c caused by an unbounded strcpy of an element's name attribute. Attackers can craft an EPUB or DAISY book with a name attribute of 511 or more characters to corrupt the stack and crash the reader when opened.21hCVE-2026-760778.1 HIG—
——0ASN1SCC is an open source ASN.1 compiler for embedded systems. Prior to 4.7.0.1, the XER tokenizer NT() in asn1crt/asn1crt_encoding_xer.c, which is reached by all XER decode paths, copies tag characters into a fixed char Value[100] field without a length bound and reads input and lookahead bytes without checking the buffer count. A crafted XER message with an overlong tag can overwrite the tokenizer's stack frame, while a truncated tag or unterminated processing-instruction or comment sequence can read beyond the input and may cause a CPU spin. The flaws can disclose adjacent memory, corrupt stack data, crash or hang the decoder, and potentially permit code execution. This issue is fixed in version 4.7.0.1.23hCVE-2026-48173—3.4%
——1In the NAS message handler, improper validation of the length field in NAS message causes memory corruption2dCVE-2026-870408.3 HIG21.3%
——6The nRF link-layer receive paths of the open-source Bluetooth LE Controller did not validate the on-air LENGTH field of a received PDU against the maximum receive length that was used to program the radio. isr_rx_pdu() in subsys/bluetooth/controller/ll_sw/nordic/lll/lll_conn.c enqueued any non-empty data PDU after only the sequence-number and (for encrypted links) MIC checks, and the corresponding isr_rx() handlers in lll_central_iso.c, lll_peripheral_iso.c, lll_sync_iso.c and lll_scan_aux.c did the same for ISO and extended-advertising PDUs. The nRF radio stores the received header verbatim and truncates only the payload at PCNF1.MAXLEN, so a frame declaring more octets than were configured leaves a node buffer whose len field describes more data than the buffer holds.
An attacker within radio range that can emit a hand-crafted link-layer PDU — for a connection, any peer that establishes an unencrypted LE connection to a connectable advertiser; for CONFIG_BT_CTLR_SYNC_ISO, any broadcaster the device is synchronised to — can set the length byte up to 255 while the controller has programmed a much smaller maximum (lll->dle.eff.max_rx_octets, which is 27 until a Data Length Update, or the negotiated cis_lll->rx.max_pdu). No pairing, authentication or user interaction is required. On encrypted links the CCM MIC check normally rejects such a frame first, so the exposure is on unencrypted traffic, which is why the added check is placed after decryption.
The unchecked length reaches hci_acl_encode() in subsys/bluetooth/controller/hci/hci.c, which performs net_buf_add(buf, pdu_data->len) followed by a memcpy() of that many bytes out of the node_rx pool element. Because CONFIG_BT_CTLR_DATA_LENGTH_MAX and CONFIG_BT_BUF_ACL_RX_SIZE both default to 27, this is an out-of-bounds read of up to roughly 228 bytes past the received PDU and a corresponding out-of-bounds write past the HCI ACL buffer into neighbouring buffers of the same pool; the tailroom test in net_buf_simple_add() is only enforced when CONFIG_NET_BUF_HARDENING (or CONFIG_ASSERT) is enabled. On the ISO paths the same unchecked length makes isoal_rx_append_to_sdu() read past the ISO node buffer and emit adjacent controller RAM to the host as ISO data. The practical result is remote memory corruption and controller crashes, plus disclosure of controller memory into the host data path.
The fix rejects any received PDU whose length exceeds the value that was used to configure the radio reception. Note that lll_sync.c (periodic advertising sync reception) was not changed and still enqueues received PDUs without an equivalent bound.2dCVE-2026-1216036.5 MED55.6%
——17Solanum before commit 2ea1382 contains a buffer overflow vulnerability in ms_kill() that allows malicious linked servers to corrupt memory by sending an overlong kill reason. Attackers controlling a rogue or compromised peer server can send a reason exceeding KILLLEN that overflows a static 512-byte buffer, crashing the ircd or potentially achieving remote code execution.3dCVE-2026-1091614.9 MED22.8%
——7Insufficient bounds checking in the Digital I/O function may allow a remote attacker with high privileges to cause a denial of service.3d
