  3. CVE-2024-53175
In the Linux kernel, the following vulnerability has been resolved: ipc: fix memleak if msg_init_ns failed in create_ipc_ns Percpu memory allocation may failed during create_ipc_ns however this fail is not handled properly since ipc sysctls and mq sysctls is not released properly. Fix this by release these two resource when failure. Here is the kmemleak stack when percpu failed: unreferenced object 0xffff88819de2a600 (size 512): comm "shmem_2nstest", pid 120711, jiffies 4300542254 hex dump (first 32 bytes): 60 aa 9d 84 ff ff ff ff fc 18 48 b2 84 88 ff ff `.........H..... 04 00 00 00 a4 01 00 00 20 e4 56 81 ff ff ff ff ........ .V..... backtrace (crc be7cba35): [<ffffffff81b43f83>] __kmalloc_node_track_caller_noprof+0x333/0x420 [<ffffffff81a52e56>] kmemdup_noprof+0x26/0x50 [<ffffffff821b2f37>] setup_mq_sysctls+0x57/0x1d0 [<ffffffff821b29cc>] copy_ipcs+0x29c/0x3b0 [<ffffffff815d6a10>] create_new_namespaces+0x1d0/0x920 [<ffffffff815d7449>] copy_namespaces+0x2e9/0x3e0 [<ffffffff815458f3>] copy_process+0x29f3/0x7ff0 [<ffffffff8154b080>] kernel_clone+0xc0/0x650 [<ffffffff8154b6b1>] __do_sys_clone+0xa1/0xe0 [<ffffffff843df8ff>] do_syscall_64+0xbf/0x1c0 [<ffffffff846000b0>] entry_SYSCALL_64_after_hwframe+0x4b/0x53

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ipc: se corrige la fuga de memoria si msg_init_ns falla en create_ipc_ns. La asignación de memoria por CPU puede fallar durante create_ipc_ns; sin embargo, este error no se gestiona correctamente, ya que ipc sysctls y mq sysctls no se liberan correctamente. Solucione esto liberando estos dos recursos cuando falle. Aquí está la pila kmemleak cuando percpu falló: objeto sin referencia 0xffff88819de2a600 (tamaño 512): comm "shmem_2nstest", pid 120711, jiffies 4300542254 volcado hexadecimal (primeros 32 bytes): 60 aa 9d 84 ff ff ff ff ff fc 18 48 b2 84 88 ff ff `.........H..... 04 00 00 00 a4 01 00 00 20 e4 56 81 ff ff ff ff ........ .V..... backtrace (crc be7cba35): [] __kmalloc_node_track_caller_noprof+0x333/0x420 [] kmemdup_noprof+0x26/0x50 [] configuración_mq_sysctls+0x57/0x1d0 [] copia_ipcs+0x29c/0x3b0 [] creación_nuevos_espacios_de_nombres+0x1d0/0x920 [] copia_espacios_de_nombres+0x2e9/0x3e0 [] proceso_de_copia+0x29f3/0x7ff0 [] clon_de_kernel+0xc0/0x650 [] __do_sys_clone+0xa1/0xe0 [] hacer_llamada_al_sistema_64+0xbf/0x1c0 [] entrada_LLAMADA_AL_SISTEMA_64_después_de_hwframe+0x4b/0x53
