Technical description

In the Linux kernel, the following vulnerability has been resolved: staging: rtl8723bs: fix OOB reads in IE loops in issue_assocreq() and join_cmd_hdl() Two IE parsing loops are missing the header bounds checks before they dereference pIE->length: - issue_assocreq() walks pmlmeinfo->network.ies to build the association request. If the stored IE data ends with only an element_id byte and no length byte, pIE->length is read one byte past the end of the buffer. - join_cmd_hdl() walks pnetwork->ies during station join and has the same problem under the same conditions. Both buffers are filled from AP beacon and probe-response frames, so a malicious AP that sends a truncated final IE can trigger the issue. Apply the two-guard pattern established in update_beacon_info(): 1. Break if fewer than sizeof(*pIE) bytes remain. 2. Break if the IE's declared data extends past the buffer end.

———In geniezone, there is a possible information disclosure due to a missing bounds check. This could lead to local information disclosure if a malicious actor has already obtained the System privilege. User interaction is needed for exploitation. Patch ID: ALPS10867524 / ALPS10876355; Issue ID: MSV-6674.7h CVE-2026-862273.1 LOW

———A weakness has been identified in valkey-io valkey up to 9.0.5/9.1.1. This affects the function kvstoreGetHashtable of the file src/kvstore.c. This manipulation of the argument didx causes out-of-bounds read. It is possible to initiate the attack remotely. The attack is considered to have high complexity. It is indicated that the exploitability is difficult. The exploit has been made available to the public and could be used for attacks. Patch name: 4691888e7fab3df128f0bde5750c9fde2ae552fa. To fix this issue, it is recommended to deploy a patch. Exploitation requires cluster mode plus attacker-controlled dump.rdb at startup (data-dir write access, replication feed, or a stored crafted RDB) - an attacker-position DoS at boot, not network pre-auth. The issue report was closed stating it "is worth fixing for the sake of memory safety… but I don't think it meets our bar for a security disclosure."10h CVE-2026-319125.5 MED

——0libpcap BPF interpreter detects neither reaching the end of the filter program buffer due to lack of a return instruction nor executing a jump instruction with an offset that translates to a pointer outside of the buffer. In particular uncommon use cases a crafted filter program can cause the interpreter to try reading the OS process memory in the 32GiB around the buffer on 64-bit architectures and in the entire address space on 32-bit architectures.2d CVE-2026-07998.7 HIG

——0In BPF instructions that load/store a value from/to a scratch memory register the register index is an unsigned 32-bit integer and must not exceed 15, but libpcap BPF interpreter does not validate the value. In particular uncommon use cases a crafted filter program can cause the interpreter to try reading and writing the OS process memory in the 16GiB starting at the current stack frame on 64-bit architectures and in the entire address space on 32-bit architectures.2d CVE-2025-156475.5 MED

——0CDT before 1.4.5 contains an out-of-bounds read vulnerability in the opposedVertexInd() function when constraint edge intersections are computed in floating point and round outside adjacent triangles. Attackers can supply nearly-degenerate constraint edges through geometry data to trigger an out-of-bounds array access that crashes the calling process.2d CVE-2025-156143.3 LOW
