Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: Net: Ethernet: ti: am65-cpsw: fixed a memory leak in certain XDP scenarios. If the XDP program does not result in XDPPASS, then we leak the memory allocated by am65cpswbuildskb. It is pointless to allocate SKB memory before runni...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: usbnet: Fix for NPE during rxcomplete. There is a missing validation of usbnetgoingaway in the critical path. The usbsubmiturb function lacks this validation, while usbnetqueueskb includes this check. This inconsistency creates a...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: can: rockchip: rkcanfdhandlerxfifooverflowint: Bail out if skb cannot be allocated. The NULL pointer check in rkcanfdhandlerxfifooverflowint has been fixed to also bail out if skb cannot be allocated...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerabilities have been resolved: ipv6: mcast: Extended RCU protection in igmp6send igmp6send can be called without RTNL or RCU being held. We have extended RCU protection so that we can safely retrieve the net pointer and avoid a potential UAF...

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...

SUSE CVE-2025-37909

In the Linux kernel, the following vulnerability has been resolved: net: lan743x: Fix memleak issue when GSO enabled Always map the skb to the LS descriptor. Previously skb was mapped to EXT descriptor when the number of fragments is zero with GSO enabled. Mapping the skb to EXT descriptor preven...

SUSE CVE-2025-37918

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btusb: avoid NULL pointer dereference in skbdequeue A NULL pointer dereference can occur in skbdequeue when processing a QCA firmware crash dump on WCN7851 0489:e0f3. 93.672166 Bluetooth: hci0: ACL memdump size589824...

SUSE CVE-2025-37959

In the Linux kernel, the following vulnerability has been resolved: bpf: Scrub packet on bpfredirectpeer When bpfredirectpeer is used to redirect packets to a device in another network namespace, the skb isn't scrubbed. That can lead skb information from one namespace to be "misused" in another...

DEBIAN-CVE-2025-37909

In the Linux kernel, the following vulnerability has been resolved: net: lan743x: Fix memleak issue when GSO enabled Always map the skb to the LS descriptor. Previously skb was mapped to EXT descriptor when the number of fragments is zero with GSO enabled. Mapping the skb to EXT descriptor preven...

UBUNTU-CVE-2025-37920

In the Linux kernel, the following vulnerability has been resolved: xsk: Fix race condition in AFXDP generic RX path Move rxlock from xsksocket to xskbuffpool. Fix synchronization for shared umem mode in generic RX path where multiple sockets share single xskbuffpool. RX queue is exclusive to...

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: mac80211: use two-phase skb reclamation in ieee80211_do_stop()

A flaw was found in the Linux kernel's mac80211 wireless subsystem. A local attacker with low privileges could trigger a condition where the system attempts to transmit data with interrupts disabled during the ieee80211dostop function. This incorrect handling of network packet buffers SKBs can le...

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...

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

A flaw was found in the Linux kernel's ath9khtc Wi-Fi driver. An issue exists where the skbtrim function, used for resetting the length of a socket buffer skb before resubmitting a USB Request Block urb, can encounter an uninitialized length value in certain error conditions. A local attacker cou...

SUSE CVE-2022-49809

In the Linux kernel, the following vulnerability has been resolved: net/x25: Fix skb leak in x25lapbreceiveframe x25lapbreceiveframe using skbcopy to get a private copy of skb, the new skb should be freed in the undersized/fragmented skb error handling path. Otherwise there is a memory leak...
