CVE-2026-45842

CVE-2026-45842 concerns the Linux kernel slip module. When rslots are configured to 0 (no receive compression), the code may allocate a NULL rstate and set rslot_limit to 0. The receive path does not guard against this, causing slhc_uncompress() to dereference comp->rstate[x] if the VJ header ...

CVE-2026-42448 wormhole receive, with --output pointing at an existing directory can be path-traversed

Magic Wormhole makes it possible to get arbitrary-sized files and directories from one computer to another. Prior to 0.24.0, there is a path traversal when a receiver who specifies "--output " where that output directory currently exists as a directory. This vulnerability is fixed in 0.24.0...

kernel: can: raw: fix ro->uniq use-after-free in raw_rcv()

A flaw was found in the Linux kernel's Controller Area Network CAN raw socket implementation. A use-after-free vulnerability can occur due to a timing window during the unregistration of CAN receive filters, allowing a freed memory region to be accessed. This could lead to system instability or a...
