CVE-2026-53363

In the Linux kernel, the following vulnerability has been resolved: xfrm: iptfs: preserve shared-frag marker in iptfsconsumefrags iptfsconsumefrags transfers paged fragments from one socket buffer to another but fails to propagate the SKBFLSHAREDFRAG flag. This is the same class of bug that was...

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 ...

USN-8390-1 linux, linux-azure, linux-azure-4.15, linux-azure-fips, linux-fips, linux-gcp-4.15, linux-gcp-fips, linux-kvm, linux-oracle vulnerability

It was discovered that the Linux kernel did not properly handle shared page fragments during socket buffer operations, collectively known as Dirty Frag. A logic flaw existed in the XFRM ESP-in-TCP subsystem and in the RxRPC networking subsystem when processing paged fragments. A local attacker...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: net: skbuff: Preserve the shared-frag marker during coalescing The skbtrycoalesce function can attach paged fragments from @from to @to. If @from has the SKBFLSHAREDFRAG flag set, the resulting @to skb may contain the same...

CVE-2026-46300 net: skbuff: preserve shared-frag marker during coalescing

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...

CVE-2026-43503 net: skbuff: propagate shared-frag marker through frag-transfer helpers

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...

CVE-2026-43503

The CVE-2026-43503 entry concerns Linux kernel net/skbuff handling: when frags are moved by frag-transfer helpers (notably __pskb_copy_fclone() and skb_shift()), the SKBFL_SHARED_FRAG flag was not propagated to the destination skb, causing destination pages to remain shared while skb_has_shared_f...
