Technical description

IBM PowerVM Hypervisor FW1120.00, FW1110.00 through FW1110.30, FW1060.00 through FW1060.80, and FW950.00 through FW950.H2 is affected by a vulnerability in the PowerVM hypervisor call interface. An attacker with root access to a guest partition can issue a specially crafted hypervisor call causing a virtual processor to become permanently unresponsive, requiring a full platform re-IPL to restore normal operation. In some cases this may also cause the guest to inject a small amount of data into hypervisor or partition memory with no attacker control over the target location. Successful exploitation results in an integrity and availability impact to the managed system.

——0IBM AIX 7.2, and 7.3 and IBM PowerVM VIOS 4.1 could allow a remote attacker to cause a denial of service due to an improper check for an array index boundary.8h CVE-2026-658328.2 HIG

——7Deskflow is a keyboard and mouse sharing app. Prior to continuous build 1.26.0.299, a remote unauthenticated Deskflow server can send kMsgDSetOptions (DSOP) values to ServerProxy::setOptions() in src/lib/client/ServerProxy.cpp so that the value following a modifier option poisons m_modifierTranslationTable, after which ServerProxy::translateKey() or ServerProxy::translateModifierMask() indexes the seven-row s_translationTable or s_masks arrays out of bounds, disclosing four bytes at an attacker-selected relative offset or crashing the connected client; an odd option count also causes an out-of-bounds OptionsList read. This issue is fixed in continuous build 1.26.0.299.3d CVE-2026-492825.1 MED

——1Capstone is a disassembly framework. Prior to version 6.0.0-Alpha9, Capstone's public `cs_insn_name()` API forwards caller-supplied instruction IDs directly to the selected architecture backend. Most backends validate the ID before indexing instruction-name tables, but the M68K and RISCV backends have missing or incomplete bounds checks. On a Capstone handle opened for M68K or RISCV, a caller-controlled invalid instruction ID can trigger an out-of-bounds read and crash the process. The demonstrated impact is availability loss in applications or bindings that expose instruction-name lookup to untrusted IDs. No code execution or data disclosure was demonstrated. Version 6.0.0-Alpha9 patches the issue.3d CVE-2026-734894.3 MED

——5Russh is a Rust SSH client & server library. Prior to 0.62.4, an authenticated SSH client can cause a denial of service by sending a pty-req channel request with more than 130 terminal-mode records. The parser in russh/src/server/encrypted.rs stores terminal modes in a fixed 130-entry [(Pty::TTY_OP_END, 0); 130] array but continues increasing the mode count, then constructs an out-of-bounds slice and panics before the application pty_request handler runs. The panic terminates the server session task without causing memory corruption. This issue is fixed in version 0.62.4.3d CVE-2026-73564—

——10frp is a fast reverse proxy. From 0.53.0 until 0.70.1, frp's optional SSH Tunnel Gateway in pkg/ssh/server.go parses an SSH exec channel request by adding 4 to an attacker-controlled four-byte big-endian length. A length of 0xFFFFFFFF makes the uint32 addition wrap to 3, defeats the payload bounds check, and causes payload[4:3] to panic in TunnelServer.handleNewChannel. When no authorized-keys file is configured, sshConfig.NoClientAuth permits an unauthenticated peer to reach this channel phase before the frp token is checked, so a single five-byte request terminates the frps process and drops every active tunnel. This issue is fixed in version 0.70.1.7d CVE-2026-537926.5 MED

——7rsync before 3.5.0 contains an out-of-bounds read vulnerability in the sender-side block matching logic that allows a malicious receiver to trigger memory access before the start of an allocated buffer by sending a crafted checksum block with a length of zero. Attackers can send a specially crafted checksum set containing a zero-length block to cause a negative offset calculation during delta computation, resulting in an out-of-bounds read of file data buffer memory on the sender side.6d
