Amazon Linux 2 : kernel (ALASKERNEL-5.15-2026-116)

high Nessus Plugin ID 351051

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of kernel installed on the remote host is prior to 5.15.220-153.252. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.15-2026-116 advisory.

In the Linux kernel, the following vulnerability has been resolved:

futex: Prevent lockup in requeue-PI during signal/ timeout wakeup (CVE-2026-52977)

In the Linux kernel, the following vulnerability has been resolved:

bpf: Fix use-after-free in offloaded map/prog info fill (CVE-2026-53089)

In the Linux kernel, the following vulnerability has been resolved:

bpf: Fix ld_{abs,ind} failure path analysis in subprogs (CVE-2026-53090)

In the Linux kernel, the following vulnerability has been resolved:

bpf: Reject BPF_MAP_TYPE_INODE_STORAGE creation if BPF LSM is uninitialized

When CONFIG_BPF_LSM=y is set, BPF inode storage maps(BPF_MAP_TYPE_INODE_STORAGE) are compiled into the kernel. However,if the BPF LSM is not explicitly enabled at boot time (e.g. omittedfrom the lsm= boot parameter), lsm_prepare() is never executed forthe BPF LSM.

Consequently, the BPF inode security blob offset(bpf_lsm_blob_sizes.lbs_inode) is never initialized and remains atits default compiled size of 8 bytes instead of being updated to avalid offset past the reserved struct rcu_head (typically 16 bytesor more).

When a privileged user creates and updates a BPF_MAP_TYPE_INODE_STORAGEmap, bpf_inode() evaluates inode->i_security + 8. This erroneouslyaliases the struct rcu_head.func callback pointer at the beginningof the inode->i_security blob. During subsequent map element cleanupor inode destruction, writing NULL to owner_storage clears the queuedRCU callback pointer. When rcu_do_batch() later executes the queuedcallback, it attempts an instruction fetch at address 0x0, triggeringan immediate kernel panic.

Fix this by introducing a global bpf_lsm_initialized boolean flagmarked with __ro_after_init. Set this flag to true inside bpf_lsm_init()when the LSM framework successfully registers the BPF LSM. Gate mapallocation in inode_storage_map_alloc() on this flag, returning-EOPNOTSUPP if the BPF LSM is in turn uninitialized.

This fail-fast approach prevents userspace from allocating inodestorage maps when the supporting BPF LSM infrastructure is absent,avoiding zombie map states. (CVE-2026-64192)
