CVE-2026-39892 cryptography has a buffer overflow if non-contiguous buffers were passed to APIs

cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. From 45.0.0 to before 46.0.7, if a non-contiguous buffer was passed to APIs which accepted Python buffers e.g. Hash.update, this could lead to buffer overflows. This vulnerability is fixed in...

CVE-2026-39892

CVE-2026-39892 affects the Python package cryptography. From 45.0.0 to before 46.0.7, passing a non-contiguous buffer to APIs that accept Python buffers (e.g., Hash.update()) could cause buffer overflows. The issue is fixed in version 46.0.7. Remediation: upgrade to cryptography 46.0.7 or later.

Cryptography vulnerable to buffer overflow if non-contiguous buffers were passed to APIs

If a non-contiguous buffer was passed to APIs which accepted Python buffers e.g. Hash.update, this could lead to buffer overflows. For example: python h = HashSHA256 b.updatebuf::-1 would read past the end of the buffer on Python 3.11...

kernel: macvlan: fix error recovery in macvlan_common_newlink()

A use-after-free vulnerability was found in the macvlan driver. When creating a macvlan interface in source mode fails after the source MAC has been added to the hash table e.g., due to an invalid interface name, the hash entry still references the freed netdevice structure. Subsequent packets...

binutils: GNU Binutils Linker elflink.c get_link_hash_entry out-of-bounds

A flaw was found in binutils. Processing a specially crafted object file with the ld linker can trigger an out-of-bounds read in the getlinkhashentry function in the bfd/elflink.c file due to an improper check, causing a crash and resulting in a denial of service...

CVE-2026-5082

Amon2::Plugin::Web::CSRFDefender versions from 7.00 through 7.03 for Perl generate an insecure session id. The generatesessionid function will attempt to read bytes from the /dev/urandom device, but if that is unavailable then it generates bytes using SHA-1 hash seeded with the built-in rand...

kernel: macvlan: fix possible UAF in macvlan_forward_source()

In the Linux kernel, the following vulnerability has been resolved: macvlan: fix possible UAF in macvlanforwardsource Add RCU protection on struct macvlansourceentry-vlan. Whenever macvlanhashdelsource is called, we must clear entry-vlan pointer before RCU grace period starts. This allows...

Ado::Sessions versions through 0.935 for Perl generates insecure session ids. The session id is generated from a SHA-1 hash seeded with the built-in rand function, the epoch time, and the PID. The PID will come from a small set of numbers, and the epoch time may be guessed, if it is not leaked fr...

Addressable has a Regular Expression Denial of Service in Addressable templates

Impact Within the URI template implementation in Addressable, two classes of URI template generate regular expressions vulnerable to catastrophic backtracking: 1. Templates using the explode modifier with any expansion operator e.g., foo, +var, var, /var, .var, ;var, ?var, &var generate patterns...

GHSA-69X8-HRGQ-FJJ8 LiteLLM: Password hash exposure and pass-the-hash authentication bypass

Impact Three issues combine into a full authentication bypass chain: 1. Weak hashing: User passwords are stored as unsalted SHA-256 hashes, making them vulnerable to rainbow table attacks and trivially identifying users with identical passwords. 2. Hash exposure: Multiple API endpoints /user/info...
