Information Exposure

Element Call is vulnerable to Information Exposure. The vulnerability is due to analytics data including full page URLs and URL fragments being sent to a configured PostHog server, which allows an attacker with access to the analytics data to obtain sensitive information such as call encryption...

Ubuntu 20.04 LTS / 22.04 LTS : Linux kernel (Azure) vulnerabilities (USN-8426-1)

The remote Ubuntu 20.04 LTS / 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8426-1 advisory. It was discovered that the Linux kernel algifaead module did not properly handle in-place cryptographic operations. This flaw is known as Cop...

Element Call reports full URLs of visited pages to analytics server

Impact Element Call versions 0.5.17 through 0.19.3 report analytics data to a PostHog server, when configured to by a posthog key in config.json or by the posthogApiHost and posthogApiKey URL parameters. Several fields of this data $initialpersoninfo, $sessionentryurl, and $currenturl were found ...

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-2026-46323 net: gro: don't merge zcopy skbs

In the Linux kernel, the following vulnerability has been resolved: net: gro: don't merge zcopy skbs skbgroreceive can currently copy frags between the source and GRO skb, without checking the zerocopy status, and in particular the SKBFLMANAGEDFRAGREFS flag. When SKBFLMANAGEDFRAGREFS is set, the...

Denial Of Service (DoS)

Netty is vulnerable to Denial of Service DoS. The vulnerability is due to unbounded accumulation of incomplete SCTP message fragments in nested CompositeByteBuf structures without limits on fragment count, size, or stream identifiers, which allows an attacker to exhaust memory and processing...

Netty: SCTP reassembly nests buffers without bound

For each non-complete SctpMessage fragment the handler does fragments.putstreamId, Unpooled.wrappedBufferfrag, byteBuf, wrapping the previous accumulator and the new slice into a new CompositeByteBuf every time. After N fragments the accumulator is an N-deep chain of composites, each holding...
