TencentOS Server 2: kernel (TSSA-2026:0418)

"The version of Tencent Linux installed on the remote TencentOS Server 2 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2026:0418 advisory. Package updates are available for TencentOS Server 2 that fix the following vulnerabilitie...

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 ...

CVE-2026-46300

The CVE-2026-46300 issue affects the Linux kernel's net: skbuff code: skb_try_coalesce() can transfer paged frags from one skb to another while losing the SKBFL_SHARED_FRAG marker, breaking the invariant relied on by ESP decryption logic. This can allow an in-place decrypt path to operate on page...

CVE-2026-46300

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...
