In the Linux kernel, the following vulnerability has been resolved:
mtd: spinand: fix memory leak of ECC engine conf
Memory allocated for the ECC engine conf is not released during spinand cleanup. Below kmemleak trace is seen for this memory leak:
unreferenced object 0xffffff80064f00e0 (size 8): comm "swapper/0", pid 1, jiffies 4294937458 hex dump (first 8 bytes): 00 00 00 00 00 00 00 00 ........ backtrace (crc 0): kmemleakalloc+0x30/0x40 _kmalloccachenoprof+0x208/0x3c0 spinandondieeccinitctx+0x114/0x200 nandeccinitctx+0x70/0xa8 nanddeveccengineinit+0xec/0x27c spinandprobe+0xa2c/0x1620 spimemprobe+0x130/0x21c spiprobe+0xf0/0x170 reallyprobe+0x17c/0x6e8 _driverprobedevice+0x17c/0x21c driverprobedevice+0x58/0x180 _deviceattachdriver+0x15c/0x1f8 busforeachdrv+0xec/0x150 _deviceattach+0x188/0x24c deviceinitialprobe+0x10/0x20 busprobedevice+0x11c/0x160
Fix the leak by calling nanddeveccenginecleanup() inside spinandcleanup().
