  1. CVE-2026-102560 9.8 Critique

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 9 · Red Hat Enterprise Linux 6 · Red Hat Enterprise Linux 7

    A flaw was found in libsoup. When the permessage-deflate WebSocket extension compresses a very large outgoing message, truncated size calculations used for GByteArray growth could wrap, causing zlib to write past the allocated buffer and resulting in a heap buffer overflow.

  2. CVE-2026-102559 8.6 Élevée

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 8 · Red Hat Enterprise Linux 9 · Red Hat Enterprise Linux 6

    A flaw was found in libsoup. When constructing a masked WebSocket client frame for a very large outgoing payload, size values passed to GByteArray allocation APIs could be truncated while the masking routine still used the full length, causing a heap buffer overflow.

  3. CVE-2026-102558 8.6 Élevée

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 8 · Red Hat Enterprise Linux 9 · Red Hat Enterprise Linux 6

    A flaw was found in libsoup. When max-incoming-payload-size is unlimited (0), SoupWebsocketConnection could grow its incoming GByteArray based on an attacker-controlled frame length until the length wrapped, causing a heap buffer overflow while reading frame data.

  4. CVE-2026-102555 8.2 Élevée

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 6 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8

    A flaw was found in libsoup. The soup_uri_decode_data_uri() function incorrectly treated base64 data-URI payloads as NUL-terminated strings when calling g_base64_decode_inplace(). If the percent-decoded payload contained embedded NUL bytes, the decoded length could remain uninitialized and be used as the size of the returned GBytes. This can lead to an out-of-bounds read or application crash when processing a crafted data URI.

  5. CVE-2026-102557 8.6 Élevée

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 8 · Red Hat Enterprise Linux 9 · Red Hat Enterprise Linux 6

    A flaw was found in libsoup. When reassembling fragmented WebSocket messages into a GByteArray, libsoup did not adequately cap total message size against the limits of the underlying buffer type. A remote peer could send fragments that caused size truncation while the implementation still used the full length, leading to heap corruption or a crash.

  6. CVE-2026-102556 8.6 Élevée

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 8 · Red Hat Enterprise Linux 9 · Red Hat Enterprise Linux 6

    A flaw was found in libsoup. When handling an incoming WebSocket Pong frame, SoupWebsocketConnection emitted the ::pong signal with a GByteArray pointer even though the signal is declared to pass a GBytes. Applications connecting a handler that follows the documented GBytes API can trigger heap corruption or a crash upon receiving a crafted Pong.

  7. CVE-2026-95520 7.1 Élevée

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 6 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8

    A heap-based buffer overflow flaw was found in rpm. Parsing a symlink entry in an untrusted RPM package whose declared RPMTAG_LONGFILESIZES value is 0xFFFFFFFFFFFFFFFF causes an integer overflow in iterReadArchiveNext() that shrinks a buffer allocation to one byte, after which the payload's independently-controlled cpio filesize field is used to write attacker-controlled data past the end of that allocation. This is reachable via rpm2cpio, rpm2archive, and rpm -qlvp on an untrusted package.

  8. CVE-2026-97029 5.7 Moyenne

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8 · Red Hat Enterprise Linux 9

    Flatpak's process ID namespace separation does not prevent a sandboxed app's kill(0, signal) or killpg(0, signal) calls from reaching processes outside the sandbox that share the same process group. A malicious or compromised Flatpak app can use this to cause denial of service by terminating processes outside its sandbox, such as the desktop shell.

  9. CVE-2026-97024 7.1 Élevée

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 7 · Red Hat Enterprise Linux 8 · Red Hat Enterprise Linux 9

    A path traversal vulnerability in Flatpak's handling of the files/etc directory during app deployment allows a malicious Flatpak app to cause certain host system files (such as passwd, group, machine-id, or resolv.conf) to be emptied or replaced with a symlink when the app is installed or upgraded. In system-wide installations, the write is performed as root.
