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...

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: can: j1939: fix errant WARNONONCE in j1939SESSIONdeactivate The statement “j1939SESSIONdeactivate should be called with a session ref-count of at least 2” is incorrect. In some concurrent scenarios, j1939SESSIONdeactivate can be...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: In the isotprcv function, there is a potential issue where race conditions may occur during CAN frame reception. When receiving a CAN frame, the current code logic does not take into account processes that are not actually runnin...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: can: mcan: pci: added the missing mcanclassfreedev function in probe/remove methods. In mcanpciremove and the error handling path of mcanpciprobe, mcanclassfreedev should be called to release resources allocated by...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: In isotpsendmsg, cmpxchg is used to serialize access to so-tx.buf. isotprelease waits for ISOTPIDLE via waiteventinterruptible and then calls kfreeso-tx.buf. If a signal interrupts waiteventinterruptible inside close when tx.stat...

Astra Linux – Vulnerability in Linux

A flaw was discovered in the CAN BCM networking protocol within the Linux kernel. A local attacker can exploit this flaw in the CAN subsystem to corrupt memory, cause the system to crash, or escalate privileges. This race condition in the net/can/bcm.c file of the Linux kernel allows for local...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: can: isotp: sanitize CAN ID checks in isotpBind. Syzbot created an environment that led to a state machine status that cannot be reached with a compliant CAN ID address configuration. The provided address information consisted of...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net/sched: actskbmod: Skip non-Ethernet packets Currently, tcfskbmodact assumes that packets use Ethernet as their L2 protocol, which is not always the case. For example, for CAN devices: bash $ ip link add dev vcan0 type vcan $ ...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: can: dev: fix skb drop check In commit a6d190f8c767 “can: skb: drop txskb if in listen-only mode”, the priv-ctrlmode element is read even on virtual CAN interfaces that do not create the structcanpriv structure during startup. Th...
