Vulnerability Title
mtd: spinand: winbond: Fix 512GW, 01GW, 01JW and 02JW ECC information
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: mtd: spinand: winbond: Fix 512GW, 01GW, 01JW and 02JW ECC information These four chips: * W25N512GW * W25N01GW * W25N01JW * W25N02JW all require a single bit of ECC strength and thus feature an on-die Hamming-like ECC engine. There is no point in filling a ->get_status() callback for them because the main ECC status bytes are located in standard places, and retrieving the number of bitflips in case of corrected chunk is both useless and unsupported (if there are bitflips, then there is 1 at most, so no need to query the chip for that). Without this change, a kernel warning triggers every time a bit flips.

Linux kernel 安全漏洞
Vulnerability Description
Linux kernel是美国Linux基金会的开源操作系统Linux所使用的内核。 Linux kernel存在安全漏洞，该漏洞源于Winbond的四款SPI NAND芯片（W25N512GW、W25N01GW、W25N01JW、W25N02JW）的ECC信息处理不当，导致每次发生位翻转时都会触发内核警告，影响系统的稳定性和性能。
