CVE-2026-63888 1 Linux 1 Linux Kernel 2026-10-26 9.8 Critical
In the Linux kernel, the following vulnerability has been resolved: scsi: target: iscsi: Fix CRC overread and double-free in iscsit_handle_text_cmd() Two latent bugs in the Text-phase handler, both present since the original LIO integration in commit e48354ce078c ("iscsi-target: Add iSCSI fabric support for target v4.1"): 1) DataDigest CRC buffer overread (4 bytes past text_in). text_in is kzalloc()'d at ALIGN(payload_length, 4). rx_size is then incremented by ISCSI_CRC_LEN to make room for the received DataDigest in the iovec, but the same (now-bumped) rx_size is passed as the buffer length to iscsit_crc_buf(): if (conn->conn_ops->DataDigest) { ... rx_size += ISCSI_CRC_LEN; } ... if (conn->conn_ops->DataDigest) { data_crc = iscsit_crc_buf(text_in, rx_size, 0, NULL); iscsit_crc_buf() walks rx_size bytes of text_in with crc32c(), so when DataDigest is negotiated it reads 4 bytes past the end of the text_in allocation. KASAN reproduces this directly on the unpatched mainline tree as slab-out-of-bounds in crc32c() called from the Text PDU path. The OOB bytes feed crc32c() and are then compared against the initiator-supplied checksum, so the value does not flow back to the attacker, but the kernel does read past the buffer on every Text PDU with DataDigest=CRC32C. Fix by passing the actual padded payload length (ALIGN(payload_length, 4)) that was used for the kzalloc(). 2) Stale cmd->text_in_ptr re-free (double-free) on ERL>0 bad DataDigest drop. On DataDigest mismatch with ErrorRecoveryLevel > 0 the handler silently drops the PDU and lets the initiator plug the CmdSN gap: kfree(text_in); return 0; cmd->text_in_ptr still points at the freed buffer. The next Text Request on the same ITT re-enters iscsit_setup_text_cmd(), which unconditionally does kfree(cmd->text_in_ptr); cmd->text_in_ptr = NULL; freeing the same pointer a second time. Session teardown via iscsit_release_cmd() has the same shape and hits the same double-free if the connection is dropped before a second Text Request arrives. On an unmodified mainline tree the bug-1 CRC overread fires first on the initial valid Text Request and perturbs the subsequent state, so #4 was isolated by building a kernel with only the bug-1 hunk of this patch applied plus temporary printk() observability around the three relevant kfree() sites. The observability prints are not part of this patch. On that build, a three-PDU Text Request sequence after login produces two back-to-back splats: BUG: KASAN: double-free in iscsit_setup_text_cmd+0x?? BUG: KASAN: double-free in iscsit_release_cmd+0x?? showing the same pointer freed in the ERL>0 drop path and again in iscsit_setup_text_cmd() (next Text Request on the same ITT) and once more in iscsit_release_cmd() (session teardown). On distro kernels with CONFIG_SLAB_FREELIST_HARDENED=y (default) the double-free becomes a remote kernel BUG(); on non-hardened kernels it corrupts the slab freelist. Fix by clearing cmd->text_in_ptr after the kfree() in the ERL>0 drop path. With both hunks applied #4 is directly observable on the stock tree without observability printks; fixing bug-1 alone would mask #4 less, not more, so the hunks are submitted together. Both fixes are one-liners. The Text PDU state machine is unchanged and the wire protocol is unaffected.
CVE-2026-116260 1 Libimobiledevice 1 Libimobiledevice 2026-10-26 7.3 High
A weakness has been identified in libimobiledevice up to 1.4.0. This issue affects the function service_receive of the file src/afc.c of the component AFC Service. Executing a manipulation can lead to double free. The attack may be performed from remote. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
CVE-2026-55653 3 Openbsd, Openssh, Redhat 12 Openssh, Openssh, Enterprise Linux and 9 more 2026-10-26 4.3 Medium
A flaw was found in OpenSSH. A malicious SSH server can exploit a double free vulnerability in the Diffie-Hellman Group Exchange (DH-GEX) client path. This occurs during FIPS (Federal Information Processing Standards) mode known-group validation when the client processes attacker-controlled DH-GEX group parameters. Successful exploitation leads to client-side process termination, resulting in a Denial of Service (DoS).

CVE-2026-78116 1 Zephyrproject 1 Zephyr 2026-10-23 5.2 Medium
The Broadcom AFBR-S50 time-of-flight sensor driver double-completes an RTIO submission when sensor data evaluation fails. In data_ready_work_handler() (drivers/sensor/broadcom/afbr_s50/afbr_s50.c), a non-STATUS_OK return from Argus_EvaluateData() calls handle_error_on_result(), which finalises the request with rtio_iodev_sqe_err(), but execution then fell through to the tail of the function and finalised the very same struct rtio_iodev_sqe a second time with rtio_iodev_sqe_ok(). Unlike the other error branches in the same function, this one did not return. Both completion helpers reach rtio_executor_done() in subsys/rtio/rtio_executor.c, which returns the submission to the pool via rtio_sqe_pool_free() and, for streaming (multishot) submissions, also releases the RX buffer with rtio_release_buffer(). The second completion therefore reads a freed rtio_iodev_sqe, pushes the same mpsc node onto the submission queue while it is already on the pool free list — splicing the two lists together — and re-submits the freed request so the next measurement is written through an already-released buffer. For one-shot submissions it emits a spurious success completion carrying stale userdata and frees the same pool entry twice. The failure branch is driven by sensor conditions rather than by host software. The vendor API documents statuses such as ERROR_ARGUS_BIAS_VOLTAGE_REINIT and ERROR_ARGUS_LASER_MONITOR_INACTIVE as transient results of harsh ambient light, so a party in front of the optical sensor can provoke the invalid-data condition without any physical contact with the board or any software access; SPI transfer errors reach the same branch. In releases before the payload.Status check was dropped, ordinary sharp distance transitions in the sensor's field of view were sufficient. Impact is corruption of the RTIO submission pool and mempool bookkeeping: aliased submissions, writes through released buffers, and duplicate completions delivered to the application. The attacker does not control the corrupted content, so the practical consequence is memory corruption and loss of availability on devices that instantiate brcm,afbr-s50, rather than directed code execution. Only builds that enable this driver are affected.

CVE-2026-57446 1 Mz-automation 1 Libiec61850 2026-10-23 5.3 Medium
libIEC61850 is an open-source implementation of IEC 61850 client and server protocols including MMS, GOOSE, Sampled Values, and R-Session. From 1.6.1 until 1.6.2, a successful MMS ObtainFile operation closes MmsObtainFileTask::fileHandle but leaves the stale non-NULL value in a task marked MMS_FILE_UPLOAD_STATE_NOT_USED. If a later ObtainFile request reuses that task and destination creation fails, MMS_FILE_UPLOAD_STATE_SEND_OBTAIN_FILE_ERROR_DESTINATION cleanup closes the stale FILE object again. Servers with the MMS file service and ObtainFile enabled can therefore be crashed remotely by the success-then-failure request sequence. This issue is fixed in version 1.6.2.
