cryptography: cryptography Subgroup Attack Due to Missing Subgroup Validation for SECT Curves
A validation flaw has been discovered in the python cryptography package. This missing validation allows an attacker to provide a public key point P from a small-order subgroup. This can lead to security issues in various situations, such as the most commonly used signature verification ECDSA and...
Security Bulletin: cryptography Missing Subgroup Validation in EC Public Keys Enables ECDH Key Leakage and ECDSA Forgery
Summary cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. Prior to 46.0.5, the publickeyfromnumbers or EllipticCurvePublicNumbers.publickey, EllipticCurvePublicNumbers.publickey, loadderpublickey and loadpempublickey functions do not verify th...
Out-of-bounds read/write in `Index` and `IndexMut` implementations
The Index and IndexMut implementations for Caja use unchecked pointer arithmetic without bounds validation. Creating a Caja with a small key and then accessing an out-of-range index causes out-of-bounds reads or writes beyond the allocated memory. This can be triggered through safe public APIs —...
CVE-2026-43054
In the Linux kernel, the following vulnerability has been resolved: scsi: target: tcmloop: Drain commands in targetreset handler tcmlooptargetreset violates the SCSI EH contract: it returns SUCCESS without draining any in-flight commands. The SCSI EH documentation scsieh.rst requires that when a...
CVE-2026-43048 HID: core: Mitigate potential OOB by removing bogus memset()
In the Linux kernel, the following vulnerability has been resolved: HID: core: Mitigate potential OOB by removing bogus memset The memset in hidreportrawevent has the good intention of clearing out bogus data by zeroing the area from the end of the incoming data string to the assumed end of the...

urllib3: urllib3 Streaming API improperly handles highly compressed data
A decompression handling flaw has been discovered in urllib3. When streaming a compressed response, urllib3 can perform decoding or decompression based on the HTTP Content-Encoding header e.g., gzip, deflate, br, or zstd. The library must read compressed data from the network and decompress it...
OPENSUSE-SU-2026:20642-1 Security update for libsodium
This update for libsodium fixes the following issues: Security fixes: - CVE-2025-15444: Cryptographic bypass via improper elliptic curve point validation bsc1256070. - CVE-2025-69277: incorrect validation of elliptic curve points certain custom cryptography or untrusted data to...
firefox: thunderbird: expat: libexpat in Expat allows attackers to trigger large dynamic memory allocations via a small document that is submitted for parsing
A memory amplification vulnerability in libexpat allows attackers to trigger excessive dynamic memory allocations by submitting specially crafted XML input. A small input 250 KiB can cause the parser to allocate hundreds of megabytes, leading to denial-of-service DoS through memory exhaustion...
