CVE-2026-74609

A flaw was found in the Linux kernel's TIPC Transparent Inter-Process Communication protocol implementation. A race condition exists in the tipcnodelinkdown function where a link pointer is cached without proper locking. This allows another process to free the link object while the cached pointer...

CVE-2026-74609

In the Linux kernel, the following vulnerability has been resolved: tipc: read le-link under the node lock in tipcnodelinkdown tipcnodelinkdown caches the link pointer before taking n-lock: struct tipclink l = le-link; / unlocked / if !l return; tipcnodewritelockn; if !tipclinkisestablishingl /...

CVE-2026-74609

CVE-2026-74609 is a use-after-free race condition in the Linux kernel's TIPC (Transparent Inter-Process Communication) subsystem, specifically in tipc_node_link_down(). The function caches the le->link pointer before acquiring n->lock, then dereferences it under the lock. A concurrent delet...

CVE-2026-74609 tipc: read le->link under the node lock in tipc_node_link_down()

In the Linux kernel, the following vulnerability has been resolved: tipc: read le-link under the node lock in tipcnodelinkdown tipcnodelinkdown caches the link pointer before taking n-lock: struct tipclink l = le-link; / unlocked / if !l return; tipcnodewritelockn; if !tipclinkisestablishingl /...

CVE-2026-74490

A flaw was found in the Linux kernel's TIPC Transparent Inter-Process Communication module. A race condition exists in the tipcpoll function when dumping trace queue state, as it does not properly hold necessary locks. This allows a local attacker to trigger a use-after-free vulnerability by...

USN-8644-2: Linux kernel (GCP) vulnerabilities

Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - File systems infrastructure; - OCFS2 file system; - B.A.T.M.A.N. meshing protocol; - SCTP protocol; - TIPC protocol...

CVE-2026-74282

A flaw was found in the Linux kernel's Transparent Inter-Process Communication TIPC component. A remote or local attacker could send an oversized connection acknowledgment ACK message, leading to an integer underflow. This underflow can cause the connection to become permanently congested,...

CVE-2026-74283

A flaw was found in the Linux kernel's Transparent Inter-Process Communication TIPC version 2 component. This vulnerability allows a local unprivileged attacker to bypass administrative permission checks when performing network link operations. Consequently, the attacker can modify critical TIPC...

CVE-2026-74255

A flaw was found in the Linux kernel's Transparent Inter-Process Communication TIPC module. This use-after-free vulnerability occurs when the tipcdisablel2media function calls synchronizenet before properly invalidating a media pointer. This timing issue allows concurrent readers to access a memo...

CVE-2026-72404

A flaw was found in the Linux kernel's TIPC UDP media bearer. This vulnerability, a Use-After-Free UAF condition, occurs because certain data structures are prematurely destroyed during teardown without proper synchronization with concurrent operations. A local attacker with network access could...

CVE-2026-74281

A flaw was found in the Linux kernel's Transparent Inter-Process Communication TIPC module. A remote attacker, acting as a peer node, could exploit this by sending specially crafted PUBLICATION messages with inverted service ranges. This oversight in validating service range bounds allows the...

CVE-2026-72299

A flaw was found in the TIPC Transparent Inter-Process Communication component of the Linux kernel. When tipcskenqueue tracepoints are active and a socket is owned by a user, the system may attempt to access already freed or dequeued socket buffers. This can lead to a kernel crash, resulting in a...
