CVE-2024-47755
Linux NVDIMM Memory Leak Vulnerability
Description

In the Linux kernel, the following vulnerability has been resolved: nvdimm: Fix devs leaks in scan_labels() scan_labels() leaks memory when label scanning fails and it falls back to just creating a default "seed" namespace for userspace to configure. Root can force the kernel to leak memory. Allocate the minimum resources unconditionally and release them when unneeded to avoid the memory leak. A kmemleak reports: unreferenced object 0xffff88800dda1980 (size 16): comm "kworker/u10:5", pid 69, jiffies 4294671781 hex dump (first 16 bytes): 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace (crc 0): [<00000000c5dea560>] __kmalloc+0x32c/0x470 [<000000009ed43c83>] nd_region_register_namespaces+0x6fb/0x1120 [libnvdimm] [<000000000e07a65c>] nd_region_probe+0xfe/0x210 [libnvdimm] [<000000007b79ce5f>] nvdimm_bus_probe+0x7a/0x1e0 [libnvdimm] [<00000000a5f3da2e>] really_probe+0xc6/0x390 [<00000000129e2a69>] __driver_probe_device+0x78/0x150 [<000000002dfed28b>] driver_probe_device+0x1e/0x90 [<00000000e7048de2>] __device_attach_driver+0x85/0x110 [<0000000032dca295>] bus_for_each_drv+0x85/0xe0 [<00000000391c5a7d>] __device_attach+0xbe/0x1e0 [<0000000026dabec0>] bus_probe_device+0x94/0xb0 [<00000000c590d936>] device_add+0x656/0x870 [<000000003d69bfaa>] nd_async_device_register+0xe/0x50 [libnvdimm] [<000000003f4c52a4>] async_run_entry_fn+0x2e/0x110 [<00000000e201f4b0>] process_one_work+0x1ee/0x600 [<000000006d90d5a9>] worker_thread+0x183/0x350
