kernel: ndisc: use RCU protection in ndisc_alloc_skb()

A vulnerability was found in the Linux kernel's IPv6 Neighbor Discovery NDISC subsystem, which manages network neighbor information. The issue arises from improper synchronization mechanisms when allocating socket buffers skbuff in the ndiscallocskb function. Specifically, the function can be...

The vulnerability of the geneve_xmit_skb() function in the drivers/net/geneve.c module of the network device support driver for Linux kernel allows a hacker to cause a service failure.

The vulnerability of the genevexmitskb function in the drivers/net/geneve.c module of the Linux kernel’s network device support driver is related to resource management errors. Exploiting this vulnerability could allow an attacker to cause service failures...

DEBIAN-CVE-2025-37992

In the Linux kernel, the following vulnerability has been resolved: netsched: Flush gsoskb list too during -change Previously, when reducing a qdisc's limit via the -change operation, only the main skb queue was trimmed, potentially leaving packets in the gsoskb list. This could result in NULL...

Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from failure to re-queue skb on wakeup failure, which could lead to a memory leak...

kernel: wifi: ath9k_htc: Use __skb_set_length() for resetting urb before resubmit

In the Linux kernel, the following vulnerability has been resolved: wifi: ath9khtc: Use skbsetlength for resetting urb before resubmit Syzbot points out that skbtrim has a sanity check on the existing length of the skb, which can be uninitialised in some error paths. The intent here is clearly ju...

kernel: Bluetooth: hci_core: Fix not checking skb length on hci_acldata_packet

A use-after-free vulnerability was found in the Linux kernel. The Bluetooth firmware isn't checked if skb contains an ACL header, otherwise the code may attempt to access some uninitialized or invalid memory past the valid skb-data...
