Technical description

In the Linux kernel, the following vulnerability has been resolved: nfc: nci: Fix uninit-value in nci_dev_up and nci_ntf_packet syzbot reported the following uninit-value access issue [1][2]: nci_rx_work() parses and processes received packet. When the payload length is zero, each message type handler reads uninitialized payload and KMSAN detects this issue. The receipt of a packet with a zero-size payload is considered unexpected, and therefore, such packets should be silently discarded. This patch resolved this issue by checking payload size before calling each message type handler codes.

——0An information leakage vulnerability exists in the Endpoint DLP component (epdlpdrv.sys) of Netskope Client for Windows prior to version R141. An internal communication channel used by the user-space hook DLL to pass messages through the kernel driver to the daemon lacked proper token-based message validation, allowing local unprivileged processes to send unauthorized queries. Additionally, a reply buffer used by the port message handler was not properly initialized before returning data, leaking residual kernel pool memory from prior allocations. A local unprivileged attacker could exploit this vulnerability to enumerate DLP configuration and feature flags, extract live session tokens, and read kernel memory fragments from other users' operations.4d CVE-2026-87647—
