Description

**Issue Overview:** 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) 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.
