CVE-2023-54105 is a vulnerability of currently unknown severity. In the Linux kernel, the following vulnerability has been resolved: can: isotp: check CAN address family in isotp_bind() Add missing check to block non-AF_CAN binds. Syzbot created some code which matched the right sockaddr struct size but used AF_XDP (0x2C) instead of AF_CAN (0x1D) in the address family field: bind$xdp(r2, &(0x7f0000000540)={0x2c, 0x0, r4, 0x0, r2}, 0x10) ^^^^ This has no funtional impact but the userspace should be notified about the wrong address family field content.. EPSS estimates a 0.18% chance of exploitation in the next 30 days.
