kernel: out of bounds read due to a missing bounds check in f2fs_xattr_generic_list of xattr.c leading to local information disclosure
In f2fs_xattr_generic_list of xattr.c, there is a possible out of bounds read due to a missing bounds check. This could lead to local information disclosure with System execution privileges needed. User interaction is not required for exploitation.Product: Android. Versions: Android kernel. Android ID: A-120551147.
An out-of-bounds (OOB) memory access flaw was found in the F2FS filesystem module in f2fs_listxattr in fs/f2fs/xattr.c. A missing bounds check before a memcpy can leak the kernel's internal information, and lead to a denial of service. The highest threat from this vulnerability is to confidentiality.
