CVE-2025-9820

Gnutls: stack-based buffer overflow in gnutls_pkcs11_token_init() function

A flaw was found in the GnuTLS library, specifically in the gnutls_pkcs11_token_init() function that handles PKCS#11 token initialization. When a token label longer than expected is processed, the function writes past the end of a fixed-size stack buffer. This programming error can cause the application using GnuTLS to crash or, in certain conditions, be exploited for code execution. As a result, systems or applications relying on GnuTLS may be vulnerable to a denial of service or local privilege escalation attacks.

Libssh: memory exhaustion via repeated key exchange in libssh

A flaw was found in libssh's handling of key exchange (KEX) processes when a client repeatedly sends incorrect KEX guesses. The library fails to free memory during these rekey operations, which can gradually exhaust system memory. This issue can lead to crashes on the client side, particularly when using libgcrypt, which impacts application stability and availability.

M17n-lib: null dereference in minput_open_im() after failed m17n_init()

A flaw was found in m17n-lib. A partial failure during library initialization can leave an internal driver pointer uninitialized. Under specific error conditions, such as system resource exhaustion or database corruption, an application attempting to open an input method dereferences this null pointer without proper validation. This issue causes the application to crash, resulting in a Denial of Service (DoS).

Bluez: bluez: stack-based out-of-bounds read in btmon via unvalidated num_keys in return_link_keys_evt()

A flaw was found in BlueZ. An out-of-bounds read vulnerability exists in the btmon Bluetooth monitor tool when processing crafted HCI Return Link Keys events. A maliciously crafted btsnoop capture file can specify a large number of link keys that exceeds the actual packet data, causing btmon to read beyond the allocated buffer and crash.

Sssd: sssd: denial of service via out-of-bounds read in autofs responder

A flaw was found in SSSD. A local attacker can exploit this vulnerability by sending a specially crafted request to the autofs responder UNIX socket. Due to improper buffer offset calculation during request parsing, the service performs an out-of-bounds memory read. This flaw can cause the autofs responder process to crash, resulting in a denial of service (DoS).

Libsoup: integer overflow in cookie expiration date handling in libsoup

A flaw was found in the cookie parsing logic of the libsoup HTTP library, used in GNOME applications and other software. The vulnerability arises when processing the expiration date of cookies, where a specially crafted value can trigger an integer overflow. This may result in undefined behavior, allowing an attacker to bypass cookie expiration logic, causing persistent or unintended cookie behavior. The issue stems from improper validation of large integer inputs during date arithmetic operations within the cookie parsing routines.

Nano: running `chmod` and `chown` on the filename allows malicious user to replace the emergency file with a malicious symlink to a root-owned file

A vulnerability was found in GNU Nano that allows a possible privilege escalation through an insecure temporary file. If Nano is killed while editing, a file it saves to an emergency file with the permissions of the running user provides a window of opportunity for attackers to escalate privileges through a malicious symlink.

Qemu-kvm: information leak in virtio devices

A flaw was found in QEMU, in the virtio-scsi, virtio-blk, and virtio-crypto devices. The size for virtqueue_push as set in virtio_scsi_complete_req / virtio_blk_req_complete / virito_crypto_req_complete could be larger than the true size of the data which has been sent to guest. Once virtqueue_push() finally calls dma_memory_unmap to ummap the in_iov, it may call the address_space_write function to write back the data. Some uninitialized data may exist in the bounce.buffer, leading to an information leak.
