TITLE

Linux of Linux Kernel Vulnerability in accessing uninitialized pointers in

Trust: 0.8

sources: JVNDB: JVNDB-2024-012555

DESCRIPTION

In the Linux kernel, the following vulnerability has been resolved: wifi: ath9k_htc: Use __skb_set_length() for resetting urb before resubmit Syzbot points out that skb_trim() has a sanity check on the existing length of the skb, which can be uninitialised in some error paths. The intent here is clearly just to reset the length to zero before resubmitting, so switch to calling __skb_set_length(skb, 0) directly. In addition, __skb_set_length() already contains a call to skb_reset_tail_pointer(), so remove the redundant call. The syzbot report came from ath9k_hif_usb_reg_in_cb(), but there's a similar usage of skb_trim() in ath9k_hif_usb_rx_cb(), change both while we're at it. Linux of Linux Kernel Exists in an uninitialized pointer access vulnerability.Service operation interruption (DoS) It may be in a state. The RUGGEDCOM RST2428P is a Layer 2 Ethernet switch based on SINEC OS with up to 28 non-blocking interfaces. SCALANCE X switches are used to connect industrial components such as programmable logic controllers (PLCs) and human-machine interfaces (HMIs). Multiple vulnerabilities exist in third-party components prior to SIEMENS SINEC OS V3.2. These vulnerabilities could be exploited to corrupt values, leading to undefined behavior or security issues
