"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ntipc: fix integer overflow in tipc_recvmsg() and tipc_recvstream()\n\nIn tipc_recvmsg(), the copy length is computed as:\n\n copy = min_t(int, dlen - offset, buflen);\n\nbuflen is size_t but min_t(int, ...) casts it to int. When buflen\nexceeds INT_MAX (e.g. 0xFFFFFFFF via io_uring provided buffers), it\nwraps negative, wins the comparison, and the negative copy length\npropagates to simple_copy_to_iter() where int-to-size_t promotion\nmakes it SIZE_MAX, triggering a WARN_ON. tipc_recvstream() has the\nsame pattern.\n\n Kernel panic - not syncing: kernel: panic_on_warn set ...\n RIP: 0010:simple_copy_to_iter+0x9e/0xd0 (net/core/datagram.c:521)\n Call Trace:\n __skb_datagram_iter+0x123/0x8b0 (net/core/datagram.c:402)\n skb_copy_datagram_iter+0x77/0x1a0 (net/core/datagram.c:534)\n tipc_recvmsg+0x3d7/0xe80 (net/tipc/socket.c:1934)\n io_recvmsg+0x47e/0xda0\n\nFix by changing min_t(int, ...) to min_t(size_t, ...) in both\nfunctions. The result is always <= (dlen - offset), which is bounded\nby TIPC maximum message size (0x1ffff bytes), so the implicit\nnarrowing on assignment to int copy is always safe."
