FAQs regarding Amazon Linux ALAS/CVE Severity
A kernel information leak flaw was identified in the scsi_ioctl function in drivers/scsi/scsi_ioctl.c in the Linux kernel. This flaw allows a local attacker with a special user privilege (CAP_SYS_ADMIN or CAP_SYS_RAWIO) to create issues with confidentiality. (CVE-2022-0494)
An information leak flaw was found in NFS over RDMA in the net/sunrpc/xprtrdma/rpc_rdma.c function in RPCRDMA_HDRLEN_MIN (7) (in rpcrdma_max_call_header_size, rpcrdma_max_reply_header_size). This flaw allows an attacker with normal user privileges to leak kernel information. (CVE-2022-0812)
Due to the small table perturb size, a memory leak flaw was found in the Linux kernel's TCP source port generation algorithm in the net/ipv4/tcp.c function. This flaw allows an attacker to leak information and may cause a denial of service. (CVE-2022-1012)
A use-after-free flaw was found in fs/ext4/namei.c:dx_insert_block() in the Linux kernel's filesystem sub-component. This flaw allows a local attacker with a user privilege to cause a denial of service. (CVE-2022-1184)
A use-after-free vulnerability was found in the Linux kernel's Netfilter subsystem in net/netfilter/nf_tables_api.c. This flaw allows a local attacker with user access to cause a privilege escalation issue. (CVE-2022-1966)
A flaw was found in hw. Incomplete cleanup of multi-core shared buffers for some Intel(r) Processors may allow an authenticated user to enable information disclosure via local access. (CVE-2022-21123)
A flaw was found in hw. Incomplete cleanup of microarchitectural fill buffers on some Intel(r) Processors may allow an authenticated user to enable information disclosure via local access. (CVE-2022-21125)
A flaw was found in hw. Incomplete cleanup in specific special register write operations for some Intel® Processors may allow an authenticated user to enable information disclosure via local access. (CVE-2022-21166)
net/netfilter/nf_tables_api.c in the Linux kernel through 5.18.1 allows a local user (able to create user/net namespaces) to escalate privileges to root because an incorrect NFT_STATEFUL_EXPR check leads to a use-after-free. (CVE-2022-32250)
The Linux kernel before 5.17.9 allows TCP servers to identify clients by observing what source ports are used. (CVE-2022-32296)
An issue was discovered in the Linux kernel through 5.18.3 on powerpc 32-bit platforms. There is a buffer overflow in ptrace PEEKUSER and POKEUSER (aka PEEKUSR and POKEUSR) when accessing floating point registers. (CVE-2022-32981)
