When building the skb list, the skb share check function frees the original skb socket buffer if it is shared. The system the...
Linux kernel 安全漏洞
The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the possibility of setting the skb pointer to null when rxrpc fails to unshare a skb, potentially leadi...

CVE-2026-46300
CVE-2026-46300 ("Fragnesia") is a local privilege escalation in the Linux kernel's ESP/XFRM (IPsec ESP-in-TCP) subsystem. The root cause is that skb_try_coalesce() fails to propagate the SKBFL_SHARED_FRAG marker when transferring paged fragments, causing ESP to skip skb_cow_data() and decrypt in ...
EUVD-2026-31535
In the Linux kernel, the following vulnerability has been resolved: net: skbuff: preserve shared-frag marker during coalescing skbtrycoalesce can attach paged frags from @from to @to. If @from has SKBFLSHAREDFRAG set, the resulting @to skb can contain the same externally-owned or page-cache-backe...

In the Linux kernel, the following vulnerability has been resolved: net: skbuff: propagate shared-frag marker through frag-transfer helpers Two frag-transfer helpers pskbcopyfclone and skbshift fail to propagate the SKBFLSHAREDFRAG bit in skbshinfo-flags when moving frags from source to...
kernel: net: skbuff: propagate shared-frag marker through frag-transfer helpers
A flaw was found in the Linux kernel's networking skbuff component. When skbtrycoalesce attaches paged fragments, it can lose the SKBFLSHAREDFRAG marker. This can lead to the Encapsulating Security Payload ESP input decrypting data in place over page-cache backed fragments, potentially resulting ...
kernel: "Dirty Frag" ESP XFRM variant is a new universal Local Privilege Escalation (LPE) vulnerability in the Linux kernel
A flaw was found in the Linux kernel's xfrm-ESP and RxRPC subsystems. Unsafe in-place cryptographic processing of shared socket buffer fragments allows a low-privileged local attacker to corrupt page-cache contents of readable files, including sensitive system files, and gain root privileges. The...

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcicore: Fixed the issue of the sentcmd skb being leaked before it was freed. The sentcmd memory was not freed before freeing hcidev, causing it to leak its contents...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerabilities have been resolved: ath11k: Fixed the issue where the skb was not dropped when an htctxcompletion error occurred. When an htctxcompletion error occurs, the skb is not discarded. This is incorrect because the completionhandler logic expects the sk...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerabilities have been resolved: ipv6: A retry logic was added in net6rtnotify. inet6rtnotify can only be called under RCU protection. This means that the route may be changed concurrently, and rt6fillnode might return -EMSGSIZE. The skb should be resized whe...
