kernel: ipc: limit next_id allocation to the valid ID range

A flaw was found in the Linux kernel. The ipcidralloc function, used in the checkpoint/restore path for SysV Inter-Process Communication IPC ID allocation, does not properly limit ID allocation to the valid range. This can result in the system attempting to dereference freed memory, leading to a...

SUSE CVE-2026-64450

In the Linux kernel, the following vulnerability has been resolved: tipc: fix out-of-bounds read in broadcast Gap ACK blocks A broadcast PROTOCOL/STATEMSG can carry a Gap ACK blocks record in its data area. tipcgetgapackblks only verifies that the record's len field is self-consistent with its...

CVE-2026-64450

CVE-2026-64450: In Linux kernel TIPC, a broadcast Gap ACK blocks record could be read out-of-bounds due to a missing check that the record fits in the message data area. The bug occurs when tipc_get_gap_ack_blks() validates the len against ugack/bgack counts but not msg_data_sz(), allowing a reco...

CVE-2026-52993

A flaw was found in the Linux kernel's Transparent Inter-Process Communication TIPC module. This vulnerability, a double-free, occurs when the tipcbufappend function incorrectly handles memory after a socket buffer skb reallocation. An attacker could potentially exploit this to cause system...

Introduction to COM usage by Windows threats

Component Object Model COM is a fundamental Windows technology used by legitimate applications for object activation, inter-process communication, automation and language-independent component reuse. Those same qualities make it useful to threat actors. Malware frequently uses COM interfaces for...
