CVE-2023-52698

  3. CVE-2023-52698
In the Linux kernel, the following vulnerability has been resolved: calipso: fix memory leak in netlbl_calipso_add_pass() If IPv6 support is disabled at boot (ipv6.disable=1), the calipso_init() -> netlbl_calipso_ops_register() function isn't called, and the netlbl_calipso_ops_get() function always returns NULL. In this case, the netlbl_calipso_add_pass() function allocates memory for the doi_def variable but doesn't free it with the calipso_doi_free(). BUG: memory leak unreferenced object 0xffff888011d68180 (size 64): comm "syz-executor.1", pid 10746, jiffies 4295410986 (age 17.928s) hex dump (first 32 bytes): 00 00 00 00 02 00 00 00 00 00 00 00 00 00 00 00 ................ 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace: [<...>] kmalloc include/linux/slab.h:552 [inline] [<...>] netlbl_calipso_add_pass net/netlabel/netlabel_calipso.c:76 [inline] [<...>] netlbl_calipso_add+0x22e/0x4f0 net/netlabel/netlabel_calipso.c:111 [<...>] genl_family_rcv_msg_doit+0x22f/0x330 net/netlink/genetlink.c:739 [<...>] genl_family_rcv_msg net/netlink/genetlink.c:783 [inline] [<...>] genl_rcv_msg+0x341/0x5a0 net/netlink/genetlink.c:800 [<...>] netlink_rcv_skb+0x14d/0x440 net/netlink/af_netlink.c:2515 [<...>] genl_rcv+0x29/0x40 net/netlink/genetlink.c:811 [<...>] netlink_unicast_kernel net/netlink/af_netlink.c:1313 [inline] [<...>] netlink_unicast+0x54b/0x800 net/netlink/af_netlink.c:1339 [<...>] netlink_sendmsg+0x90a/0xdf0 net/netlink/af_netlink.c:1934 [<...>] sock_sendmsg_nosec net/socket.c:651 [inline] [<...>] sock_sendmsg+0x157/0x190 net/socket.c:671 [<...>] ____sys_sendmsg+0x712/0x870 net/socket.c:2342 [<...>] ___sys_sendmsg+0xf8/0x170 net/socket.c:2396 [<...>] __sys_sendmsg+0xea/0x1b0 net/socket.c:2429 [<...>] do_syscall_64+0x30/0x40 arch/x86/entry/common.c:46 [<...>] entry_SYSCALL_64_after_hwframe+0x61/0xc6 Found by InfoTeCS on behalf of Linux Verification Center (linuxtesting.org) with Syzkaller [PM: merged via the LSM tree at Jakub Kicinski request]

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: calipso: corrige la pérdida de memoria en netlbl_calipso_add_pass() Si la compatibilidad con IPv6 está deshabilitada en el arranque (ipv6.disable=1), no se llama a la función calipso_init() -&gt; netlbl_calipso_ops_register() y la función netlbl_calipso_ops_get() siempre devuelve NULL. En este caso, la función netlbl_calipso_add_pass() asigna memoria para la variable doi_def pero no la libera con calipso_doi_free().
