Last modified

CVE-2024-35915 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. 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. EPSS estimates a 0.22% chance of exploitation in the next 30 days.

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.
