CVE-2026-80889
In the Linux kernel, the following vulnerability has been resolved: can: isotp: fix timer drain order, wakeup handling and txgen ordering This patch is a follow-up to commit cf070fe33bfb "can: isotp: serialize TX state transitions under so-rxlock" which addresses following sashiko-bot findings: -...
CVE-2026-72126
A flaw was found in the Linux kernel's Controller Area Network CAN ISO-TP isotp module. This vulnerability arises from a race condition where the isotprelease function can cancel a timer while it is still actively being used by isotprcv. This can lead to a use-after-free condition, which a local...
CVE-2026-72125
A flaw was found in the Linux kernel's Controller Area Network CAN ISO-TP protocol. A memory corruption vulnerability, specifically a use-after-free race condition, can occur during the unregistration of a network device. This happens when the system attempts to free a socket while a CAN filter...
CVE-2026-72124
A flaw was found in the Linux kernel's Controller Area Network CAN ISO-TP transport protocol module. A race condition in the transmit TX state machine allows for unsynchronized state transitions. This can lead to a situation where a frame or timer callback operates on an outdated state, resulting...
CVE-2026-72124
In the Linux kernel, the following vulnerability has been resolved: can: isotp: serialize TX state transitions under so-rxlock The TX state machine so-tx.state is driven from three contexts: sendmsg claiming and progressing a transfer, the RX path consuming Flow Control/echo frames, and two...

openxc/isotp-c thru commit 5a5d19245f65189202719321facd49ce6f5d46ac 2021-08-09 contains an out-of-bounds read in the ISO-TP Single Frame receive handler, where the 4-bit payload length nibble is used directly as the memcpy size without validating it against the actual CAN data length. A malicious...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: can: isotp: split the transmission timer into two parts—transmission and timeout. The timer for the transmission of isotp PDUs previously had two functions: 1. sending two consecutive frames with a specified time interval. 2...
