What is known
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
Business impact
Successful exploitation of CVE-2024-53175, a medium vulnerability (CVSS 5.5) affecting linux kernel, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.
Recommended administrator action
Confirm whether linux kernel is present and compare installed versions with the vendor advisory and NVD record. Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation. DataHouse can support version verification, managed patching, network exposure reduction, log review and backup validation for dedicated, cloud and colocated environments.
