CVE-2022-49180

The CVE-2022-49180 issue affects the Linux kernel’s LSM path, specifically a general protection fault in legacy_parse_param. The vulnerability arises when a security module (Smack) processes a recognized mount option and a following BPF hook returns -ENOPARAM, confusing the caller, while the SELi...

CVE-2022-49152

CVE-2022-49152 affects the Linux kernel XArray feature, specifically the xas_create_range() path. When an existing entry with order >= XA_CHUNK_SHIFT is present, xas_create_range() can misinterpret it as a node and dereference xa_node->parent, potentially causing a crash (general protection...
