CVE-2023-6915

Vulnerability Summary

A flaw has been found in Xen. An unprivileged guest can cause Denial of Service (DoS) of the host by sending network packets to the backend, causing the backend to crash. (CVE-2023-46838) An out-of-bounds access vulnerability involving netfilter was reported and fixed as: f1082dd31fe4 (netfilter: nf_tables: Reject tables of unsupported family); While creating a new netfilter table, lack of a safeguard against invalid nf_tables family (pf) values within `nf_tables_newtable` function enables an malicious user to achieve out-of-bounds access. (CVE-2023-6040) A Null pointer dereference problem was found in ida_free in lib/idr.c in the Linux Kernel. This issue may allow an attacker using this library to cause a denial of service problem due to a missing check at a function return. (CVE-2023-6915) An out-of-bounds memory read flaw was found in receive_encrypted_standard in fs/smb/client/smb2ops.c in the SMB Client sub-component in the Linux Kernel. This issue occurs due to integer underflow on the memcpy length, leading to a denial of service. (CVE-2024-0565) netfilter: nf_tables: fix pointer math issue in nft_byteorder_eval() (CVE-2024-0607) An out-of-bounds memory write flaw was found in the Linux kernel's Transport Layer Security functionality in how a user calls a function splice with a ktls socket as the destination. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2024-0646) In rds_recv_track_latency in net/rds/af_rds.c in the Linux kernel up to and including 6.7.1, there is an off-by-one error for an RDS_MSG_RX_DGRAM_TRACE_MAX comparison, resulting in out-of-bounds access. (CVE-2024-23849)
