CVE-2026-50722 IKEv2 Denial of Service via RSA-SHA1 (PKCS#1 RSASSA-PKCS1-v1_5) authentication payload

Libreswan, via the function RSAauthenticatehashsignaturepkcs115rsa, did not correctly verify the DER encoding of the ASN.1 digest when the IKEv2 AUTH payload was encoded using RSASSA-PKCS1-v15 RFC 8017. A remote attacker can use a variation on the Bleichenbacher attack to forge the AUTH payload...

Cmov/CmovEq on aarch64 can produce wrong results if high-bits of registers are set

Summary The aarch64 implementations of Cmov and CmovEq seem to assume that the high bits when loading a value of size smaller than a register into a register are zero-extended. However, this is not the case and these bits are unspecified. This can result in a left.cmovz&right, condition not movin...

PYSEC-2026-723 Out-of-bounds Read in OpenCV

An out-of-bounds read was discovered in OpenCV before 4.1.1 OpenCV-Python before 4.1.0.25. Specifically, variable coarsestscale is assumed to be greater than or equal to finestscale within the calc/oclcalc functions in disflow.cpp. However, this is not true when dealing with small images, leading...

Name of the Vulnerable Software and Affected Versions RustCrypto CMOV versions 0.1.1 through 0.5.3 Description The aarch64 implementations of Cmov and CmovEq in cmov/src/backends/aarch64.rs incorrectly assume that high bits are zero-extended when loading values smaller than a register. Because...

PT-2026-55410

The TIFF decoder does not place a limit on the size of PackBits-compressed data. A maliciously-crafted image can exploit this to cause a small image both in terms of pixel width/height and encoded size to make the decoder decode large amounts of compressed data...

CVE-2026-6688 FatFs Buffer Overflow via Unbounded LFN Filename Copy

FatFs R0.16 and earlier contains a downstream-caller vulnerability pattern associated with FatFs long filename handling. With LFN enabled, fno.fname can be up to 255 characters; many callers copy it into short fixed buffers without bounds checks, causing overflow. This maps to CWE-120 Buffer Copy...

CVE-2026-53232

A flaw was found in the Linux kernel's network PHY Physical Layer driver. When a PHY probing operation fails, the system does not properly clean up the SFP Small Form-Factor Pluggable upstream connection. This oversight leaves a dangling reference in the SFP bus, which could be accessed later...

CVE-2026-53186

A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA SCSI RDMA Protocol SRP component. A malicious or compromised SRP target on the InfiniBand/RoCE fabric can exploit this vulnerability by sending a specially crafted SRP response with an excessively large data length. This can...
