High impact if exploited, but EPSS currently rates exploitation as unlikely (5.42%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Multiple integer overflows in the lzo1x_decompress_safe function in lib/lzo/lzo1x_decompress_safe.c in the LZO decompressor in the Linux kernel before 3.15.2 allow context-dependent attackers to cause a denial of service (memory corruption) via a crafted Literal Run.
